The first month Tan had his new phone, he downloaded 5 apps on it. Six months later, he has 22 apps on his phone. What is the percent
ncrease in the number of apps Tan has on his phone?

The x-intercept is 5 and the y-intercept is 2.

The standard form of the line is 2x + 5y = 10.

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis. In other words, the x -intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0.

Hence, the x-intercept is 5 and the y-intercept is 2.

Let's find the equation in standard form.

Ax + By = C

where

Using slope intercept form,

y = mx + b

where

Hence, using (5, 0) and (0, 2)

m = 2 - 0 / 0 - 5

m = - 2 / 5

Therefore.

y = - 2 / 5x + 2

Hence, let's multiply through by 5 to eliminate the fraction

5y = -2x + 10

Therefore, the standard form is as follows:

2x + 5y = 10

A significance test tells the researcher how likely it is that the results of the experiment occurred by chance alone. This is the correct option among the given options.

Significance testing is a statistical method used to determine whether a result or relationship in data is significant or not. It informs you whether there is sufficient evidence to reject the null hypothesis that there is no difference between two groups or no association between two variables.

The null hypothesis is always that there is no difference between the groups or no relationship between the variables. A significance test assesses how likely it is that the null hypothesis is true based on the sample data.

If the probability of getting such data is low, we reject the null hypothesis and accept the alternative hypothesis that there is a difference or an association between the variables.

The manufacturer would lose a total profit of $100,000 and a per-unit profit of $10 by producing 70,000 units instead of the demanded 80,000 units.

To calculate the total profit and per-unit profit lost, we need to consider the difference between the actual production and the demand, as well as the profit per unit.

Let's assume the profit per unit is $10.

The manufacturer produces 70,000 units, but the demand is for 80,000 units, resulting in a shortage of 10,000 units.

Total profit lost = shortage * profit per unit = 10,000 * $10 = $100,000

Therefore, the total profit lost in this scenario is $100,000.

To calculate the per-unit profit lost, we divide the total profit lost by the shortage:
Per-unit profit lost = total profit lost / shortage = $100,000 / 10,000 = $10

Therefore, the per-unit profit lost in this scenario is $10.

By understanding the difference between the actual production and the demand, as well as the profit per unit, we can determine the total profit and per-unit profit lost when producing fewer units than the demand.

Answer: Answer and explanation in picture

Step-by-step explanation:

By finding the unit rate, we can see that the total cost for 10 days is 400 dollars.

First, we know that the cost of renting the cars for 3 days is $120, then we can get the unit rate (cost for a single day) if we take the quotient between the total cost and the number of days, we will get:

$120/3 = $40

Then the cost of 10 days of rent is 10 times the number we found above, then the cost for renting the car 10 days is:

Cost = $40*10

Cost = $400

The cost of renting the car for 10 days is 400 dollars.

Part 1: You will need to find the average by adding 108, 72, and 95. This will give you 275. Now you divide the sum by the amount of numbers there are which is 3 numbers. 275/3 would be 91.6

Part 2: Now that you have all four numbers you should repeat the process, 108 + 72 + 95 + 91.6 which is 366.6 now divide by four, and you have 91.65.

The probability that the randomly selected sample will have less than 97.5% of the units that can hold at least 400 lbs of weight before breaking is 2.4249.

What is the binomial distribution?

In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n separate experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p.

Here, we have

Given: For one product, 98% of all the units made at a particular factory can hold at least 400 lbs. of weight before breaking to check the product, quality control selects a random sample of 300 units made at the factory and determines whether or not the product can hold at least 400 lbs.

p = 0.98

q = 1 - p = 1 - 0.98 = 0.02

n = 300

Using the binomial distribution,

Standard deviation = σ = √npq = √300 × 0.98 × 0.02 = 2.4249

Standard deviation = σ = 2.4249

Hence, the probability that the randomly selected sample will have less than 97.5% of the units that can hold at least 400 lbs of weight before breaking is 2.4249.

To determine Km from a double-reciprocal plot, you would choose option (A) which is to multiply the reciprocal of the x-axis intercept by -1.

In the double-reciprocal plot equation, the x-axis intercept is -1/Km, and the y-axis intercept is 1/Vmax. Therefore, if you take the reciprocal of the x-axis intercept, you get -Km, and multiplying it by -1 gives you Km.

This method is preferred because it is more accurate than estimating Km based on the position of the curve on the plot or by taking the x-axis intercept where V0 = 1/2 Vmax, which can be influenced by experimental error.

The width of a confidence interval is primarily determined by the chosen confidence level, sample size, and variability of the data.

1. Confidence level: The confidence level represents the level of certainty desired in the estimation. A higher confidence level, such as 95% or 99%, requires a wider interval to capture a larger range of possible values within that level of confidence. Conversely, a lower confidence level, such as 90%, allows for a narrower interval.

2. Sample size: Increasing the sample size generally leads to a narrower confidence interval. With a larger sample, there is more data available to estimate the population parameter, resulting in a more precise estimate and reducing the margin of error.

3. Variability of the data: Higher variability in the data, indicated by a larger standard deviation or greater spread, requires a wider confidence interval. This is because a larger range of possible values is needed to account for the uncertainty associated with more variable data.

By adjusting these factors, researchers can control the width of the confidence interval, striking a balance between the desired level of confidence and the precision of the estimate.

To evaluate the integral of (x-2)(x²+4) dx, we expand the expression and simplify it further.

Expanding the expression, we get x³+4x-2x²-8. Now we can rewrite the integral as the sum of integrals of each term: ∫(x³+4x-2x²-8) dx.

To find the integral of each term, we use the power rule for integration. The integral of x^n is (1/(n+1))x^(n+1), where n is the exponent.

Integrating x³, we get (1/4)x^4. Integrating 4x, we get 2x². Integrating -2x², we get (-2/3)x³. Integrating -8, we get -8x.

Now, we can put together the individual integrals to find the integral of the entire expression. The final result is:

(1/4)x^4 + 2x² - (2/3)x³ - 8x + C,

where C is the constant of integration.

Therefore, the integral of (x-2)(x²+4) dx is given by (1/4)x^4 + 2x² - (2/3)x³ - 8x + C.

The total number of ways to distribute all the fruits to the 30 children, ensuring each child who prefers apples gets at least 2 apples and each child who prefers oranges gets at least 2 oranges, is given by the product of C(29, 9) and C(59, 19).

To find the total number of ways, we can consider the distribution of apples and oranges separately. For the children who prefer apples, we need to distribute 20 apples among 10 children, with each child receiving at least 2 apples. This can be calculated using the stars and bars combinatorial technique. Similarly, for the children who prefer oranges, we need to distribute 40 oranges among 20 children, with each child receiving at least 2 oranges.

The number of ways to distribute the apples can be calculated as C(20+10-1, 10-1) = C(29, 9). Likewise, the number of ways to distribute the oranges can be calculated as C(40+20-1, 20-1) = C(59, 19). To find the total number of ways to distribute both fruits, we multiply these two values together.

Therefore, the total number of ways to distribute all the fruits to the 30 children while satisfying the given conditions is C(29, 9) x C(59, 19).
