To bring the outside temperature from -20 degrees Fahrenheit to 0 degrees Fahrenheit, a change of +20 degrees Fahrenheit is needed.

The temperature scale used in the US is the Fahrenheit scale. In this scale, the freezing point of water is 32 degrees Fahrenheit, while the boiling point is 212 degrees Fahrenheit.

A change of 1 degree Fahrenheit is equivalent to a change of 5/9 degree Celsius. Therefore, to bring the temperature from -20 degrees Fahrenheit to 0 degrees Fahrenheit, we need to add 20 degrees Fahrenheit.

This means the temperature would have to increase by 20 degrees Fahrenheit to reach 0 degrees Fahrenheit.

The average weight of 333 llamas is 190190190 kilograms more than the average weight of one okapi. One okapi + one llama = 450 kgs

3 llama = one okapi + 190

one okapi = 450 kgs - one llama

3 llama = 450 kgs - one llama +190 kgs

4 llamas = 640 kgs

1 llama = 160 kgs

1 okapi = 450 kgs - 160 kgs

1 okapi = 290 kgs

A technique known as a weighted average accounts for the varied levels of significance of the values in a data collection. Each number in the data set is multiplied by a predefined weight before the final computation is completed when calculating a weighted average.

A weighted average, in which each value in a data collection is given an equal weight, can be more accurate than a simple average.

A sequence of transformation that would move ΔABC onto ΔDEF is: D. a dilation by a scale factor of 1/2, centered at the origin, followed by a 90° clockwise rotation about the origin.

In Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

In this scenario an exercise, we would dilate the coordinates of the pre-image by applying a scale factor of 1/2 that is centered at the origin as follows:

Ordered pair B (-4, 2) → Ordered pair B' (-4 × 1/2, 2 × 1/2) = Ordered pair B' (-2, 1).

In Mathematics and Geometry, a rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction;

(x, y)                               →            (y, -x)

Ordered pair B' (-2, 1)   →          E (1, 2)

The average speed for the whole journey from Southhampton to Basingstoke is approximately 46.67 mph.

To calculate the average speed for the whole journey, we need to consider the total distance traveled and the total time taken. In this case, Anna drove 35 miles from Southhampton to Basingstoke.

Let's calculate the time taken for each segment of the journey:

For the first 5 miles, Anna drove at an average speed of 20 mph. The time taken for this segment can be calculated as follows:

Time = Distance / Speed

Time = 5 miles / 20 mph

Time = 0.25 hours

For the remaining 30 miles, Anna drove at an average speed of 60 mph. The time taken for this segment can be calculated as follows:

Time = Distance / Speed

Time = 30 miles / 60 mph

Time = 0.5 hours

Now, we can calculate the total time taken for the whole journey by summing up the times for each segment:

Total Time = Time for first segment + Time for second segment

Total Time = 0.25 hours + 0.5 hours

Total Time = 0.75 hours

Next, we calculate the average speed for the whole journey by dividing the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 35 miles / 0.75 hours

Average Speed ≈ 46.67 mph

There is enough proof to indicate that the percentage of newsletter readers who possess a Rolls Royce is less than 69%.

The null hypothesis is that p = 0.69, meaning that 69% of the newsletter readers own a Rolls Royce. The alternative hypothesis is that p < 0.69, meaning that less than 69% of the newsletter readers own a Rolls Royce.

We can use a one-tailed z-test to test the hypothesis. Assuming a sample size of n = 100, if we observe fewer than 69 Rolls Royces in our sample, we can reject the null hypothesis.

Using a z-test, we can calculate the z-score by using the formula:

z = (p' - p) / sqrt(p * (1 - p) / n)

where p' is the sample proportion, p is the hypothesized proportion, and n is the sample size.

At a significance level of 0.10, the critical z-value is -1.28. If the calculated z-score is less than -1.28, we can reject the null hypothesis.

If we conduct a survey of 100 newsletter readers and find that 58 of them own a Rolls Royce, the sample proportion would be p' = 0.58. Calculating the z-score, we get:

z = (0.58 - 0.69) / sqrt(0.69 * 0.31 / 100) = -1.83

Since -1.83 is less than -1.28, we can reject the null hypothesis and conclude that there is sufficient evidence to suggest that fewer than 69% of the newsletter readers own a Rolls Royce.

Step-by-step explanation:

Step-by-step explanation:

qu = 5y - 4

and qt is half of qu

so

qt =  \(\frac{5y - 4}{2}\)

Answer:

QT = 8

Step-by-step explanation:

the sides of a rhombus are congruent , then

PS = RS ( substitute values )

3y - 1 = 2y + 3 ( subtract 2y from both sides )

y - 1 = 3 ( add 1 to both sides )

y = 4

The diagonals of a rhombus bisect each other

QS = 5y - 4 = 5(4) - 4 = 20 - 4 = 16

then

QT = \(\frac{1}{2}\) QS = \(\frac{1}{2}\) × 16 = 8

Answer:

B. The population has increased by 105% each year since 1980.

D. Each year since 1980, the population is 105% of the population of the previous year.

E. Each year since 1980, the population is 1.05 times the population of the previous year.

Step-by-step explanation:

From the question, we are given the exponential function:

The exponential function P(t)=2000(1.05)^t models the population of the town since 1980.

Exponential growth rate =

P(t) = P(1 + r)^t

Where r = growth rate in percentage

P(t) = Size of the population after t years

t = time in years

Hence,

From the formula above, we can say =

1 + r = 1.05

r = 1.05 - 1

r = 0.05

Converting to percentage = 0.05 × 100 = 5%

1.05 can also converted to percentage and this = 1.05 × 100 = 105 %

The population has increased by 105% each year since 1980.

Based on the probability of selecting a white card, the number of times Leo will select a white card out of 300 times is 100 times.

Probability refers to the likelihood or chance of having a desired outcome when there are many possible outcomes.

Probability can be expressed as a ratio, fraction, or percentage, as it ranges between zero and one.

The number of red cards = 10

The number of black cards = 20

The number of yellow cards = 20

The number of white cards = 25

The total number of red, black, yellow, and white cards = 75

The probability of selecting a white card among 75 cards = 25/75

Thus, the number of times a white card can be selected from 300 selections with replacement based on the probability of a white card being selected is 100 times (300 x 25/75).

False. All values in a dataset with a normal distribution can be converted to a z-score.

False. All values in a dataset with a normal distribution can be converted to a z-score. The z-score standardizes the data, allowing for comparisons across different distributions by representing the number of standard deviations a data point is away from the mean.

A continuous random variable that tends to cluster around a centre or average value with a particular degree of spread or variation is described by the normal distribution, commonly referred to as the Gaussian distribution. The maximum frequency is near the mean and decreases in frequency as one moves farther away from the mean in both directions. It is a symmetrical bell-shaped curve.

The standard normal distribution, in which the mean and standard deviation are both 0, is a particular instance of the normal distribution. The standard score, also referred to as the z-score, is a measurement of how many standard deviations a data point deviates from the distribution's mean. The difference between the observation's value and the mean is used to calculate it.

False. All values in a dataset with a normal distribution can be converted to a z-score.

The z-score transformation is used precisely to transform values from a normal distribution to a standard normal distribution, which has a mean of 0 and a standard deviation of 1.

All values in a dataset with a normal distribution can be converted to a z-score.

The statement "not all values in a dataset with a normal distribution can be converted to a z-score" is false.

A z-score represents the number of standard deviations a data point is away from the mean of a distribution and can be calculated for any value within a normal distribution.

In fact, the conversion of values to z-scores is a common method of standardizing data for statistical analysis.
To calculate a z-score, you subtract the mean of the distribution from the individual value and then divide the result by the standard deviation of the distribution.

This transformation allows for easier comparison between data points and across different datasets.

Z-scores can also be used to calculate probabilities and determine the likelihood of certain events occurring within a distribution.
While it is true that some datasets may not follow a normal distribution, this does not mean that z-scores cannot be calculated for all values within the dataset.

The distribution is not normal, other statistical techniques such as transformation or non-parametric tests may be necessary.

A normally distributed dataset, every value can be converted to a z-score, allowing for standardized comparisons and analysis.

In mathematics, an expression is a combination of numbers, symbols, and/or variables that can be evaluated to produce a value. Expressions can also include functions, such as sin(x) or log(y), as well as operators like multiplication (*), division (/), and exponentiation (^). Expressions can be used to represent mathematical formulas, equations, and relationships in a concise and symbolic way, making them easier to work with and manipulate using mathematical tools and techniques.

Here,

If we know the value of d, we can calculate the total time Elise spent riding Maximum Velocity by simply multiplying the ride time by the number of rides.

For example, if Elise rode Maximum Velocity 3 times, the total time she spent on the ride would be:

145 seconds/ride x 3 rides = 435 seconds

So, using the expression from the previous answer, we can substitute the value of d to get the actual calculation:

Total time = 145d seconds

How many grams of grain will there be in 2.4 kg of shelled hazelnuts?

Step 1

Convert kg to g

1 kg = 1000g

2.4 g = x

Cross Multiply

x = 2.4 × 1000g = 2400g

Step 2

An 800 gram sample of shelled hazelnuts has 500 grams of grain.

Hence,

800g hazelnuts = 500 gram of grain

2400g hazelnuts = x

Cross Multiply

800x = 2400g × 500g

x = 2400g × 500g/800

x = 1500 grams of grain
