Answer:

Step-by-step explanation:

we are given that one angle is 40 degrees. The right angle below that is 90 degrees. Right angles will always equal 90 degrees. with the two angles how do we solve. Triangles no matter what will always be 180 degrees so,

40+90+x=180

130+x=180

-130     -130

x=50 degrees

Answer:

b

Step-by-step explanation:

..........................................

Answer: Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

Step-by-step explanation: To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Domain: (-4, 4) Range: (0,4)

Step-by-step explanation:

Domain is the furthest left and right points on the x-axis while the range is the same but instead of it being the x-axis, it would be the y-axis. The graph shows -4 to 4 being the domain and 0 to 4 being the range.

To find the sum of percentages, you cannot simply add the numbers together as you would with regular numbers.

Percentages represent proportions or ratios, so they must be converted to their corresponding decimal or fraction forms before adding them.

To solve 12% + 3%, you need to convert each percentage to its decimal form and then add the decimals together.

Here's the correct approach:

12% = 12/100 = 0.12

3% = 3/100 = 0.03

Now, add the decimals:

0.12 + 0.03 = 0.15

Therefore,

The value of 12% + 3% is 0.15 or 15%.

Answer:

y = (1/2)x

Step-by-step explanation:

y = mx + b

The line passes through point (0, 0), so b = 0

y = mx

Going from point (0, 0) to point ( 2, 1), rise = 1, and run = 2.

slope = rise/run = 1/2

\(\stackrel{f(x)}{y}~~ = ~~2x^2+4x\hspace{5em}\stackrel{\textit{quick switcheroo}}{x~~ = ~~2y^2+4y} \\\\\\ x=2(y^2+2y)\implies \cfrac{x}{2}=y^2+2y\impliedby \begin{array}{llll} \textit{now let's complete the square}\\ \textit{to make it a perfect square trinomial}\\ \textit{by using our good friend, Mr "0"} \end{array} \\\\\\ \cfrac{x}{2}=y^2+2y(+1^2-1^2)\implies \cfrac{x}{2}=y^2+2y+1-1\implies \cfrac{x}{2}=(y^2+2y+1)-1\)

\(\cfrac{x}{2}+1=(y^2+2y+1^2)\implies \cfrac{x}{2}+1=(y+1)^2\implies \sqrt{\cfrac{x}{2}+1}=y+1 \\\\\\ \sqrt{\cfrac{x+2}{2}}=y+1\implies \sqrt{\cfrac{x+2}{2}}-1=y~~ = ~~f^{-1}(x)\)

What is Function?

A relation between a collection of inputs and outputs is known as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.

An example of a rule is a function, which produces one output for a single input.

If the graph of a function is symmetric with respect to the y-axis, then it is said to be an even function. Otherwise, it is odd function.

The probability that X is less than or equal to 48 is approximately 0.023.

To use the normal approximation, we first need to check if the conditions are met:

1. The sample size is large enough: n*p = 93*0.48 = 44.64 and n*(1-p) = 93*0.52 = 48.36, both greater than 10.

2. The observations are independent: we assume that the sample is random and that the sample size is less than 10% of the population size.

Given these conditions, we can use the normal distribution to approximate the binomial distribution.

We standardize X using the formula:

z = \((X - n*p) / \sqrt{(n*p*(1-p)) }\)

Substituting the values, we get:

z = (48 - 93*0.48) / sqrt(93*0.48*0.52) = -1.99

Using a standard normal distribution table or calculator, we can find the probability:

P(X ≤ 48) ≈ P(z ≤ -1.99) = 0.023

Therefore, the probability that X is less than or equal to 48 is approximately 0.023.

Answer:

the answer is 106

Step-by-step explanation:

4558÷43=106

It looks like the integral is

\(\displaystyle 6 \int yz\cos(x) \, ds\)

With \(x=t\), \(y=\cos(t)\), and \(z=\sin(t)\), the line element is

\(ds = \sqrt{\left(\dfrac{dx}{dt}\right)^2 + \left(\dfrac{dy}{dt}\right)^2 + \left(\dfrac{dz}{dt}\right)^2} \, dt = \sqrt2 \, dt\)

and so

\(\displaystyle 6 \int yz\cos(x) \, ds = 6\sqrt2 \int_0^\pi \cos^2(t) \sin(t) \, dt\)

Substitute \(u = \cos(t)\) and \(du=-\sin(t)\,dt\), then

\(\displaystyle 6 \int yz\cos(x) \, ds = -6\sqrt2 \int_1^{-1} u^2 \, du = 12\sqrt2 \int_0^1 u^2 \, du = \boxed{4\sqrt2}\)

where in the second-to-last equality, we have

\(\displaystyle -\int_1^{-1} = \int_{-1}^1\)

and

\(\displaystyle \int_{-1}^1 u^2 \, du = 2 \int_0^1 u^2\,du\)

a) The z-score for a shoe size of 7.5 is approximately -0.4.

b) The shoe size corresponding to a z-score of 1.3 is approximately 9.625.

c) The z-score for a shoe size of 9 is approximately 0.8.

d) The shoe size corresponding to a z-score of -1.5 is approximately 6.125.

e) To find the shoe size representing the 80th percentile, we need to determine the corresponding z-score using a z-score table or calculator and then use the formula x = (z * standard deviation) + mean.

a) To calculate the z-score, we use the formula: z = (x - mean) / standard deviation. For a shoe size of 7.5, the z-score would be: z = (7.5 - 8) / 1.25 = -0.5 / 1.25 = -0.4.

b) To find the shoe size with a z-score of 1.3, we rearrange the formula: x = (z * standard deviation) + mean. Plugging in the values, we get: x = (1.3 * 1.25) + 8 = 1.625 + 8 = 9.625.

c) For a shoe size of 9, the z-score is: z = (9 - 8) / 1.25 = 1 / 1.25 = 0.8. The percentile can be found using a z-score table or calculator.

d) With a z-score of -1.5, we can use the same formula as before: x = (z * standard deviation) + mean. Plugging in the values, we get: x = (-1.5 * 1.25) + 8 = -1.875 + 8 = 6.125. The percentile can be found using a z-score table or calculator.

e) To find the shoe size representing the 80th percentile, we can use the inverse of the z-score formula: x = (z * standard deviation) + mean. The z-score corresponding to the 80th percentile can be found using a z-score table or calculator.

The correlation coefficient (r) for the given data is 0.926, indicating a strong positive linear relationship between temperature (X) and plant growth (Y).

The calculated correlation coefficient of 0.926 indicates a strong positive linear relationship between temperature (X) and plant growth (Y). The correlation coefficient ranges from -1 to 1, where values close to 1 indicate a strong positive correlation. In this case, a value of 0.926 suggests that as temperature increases, the amount of plant growth also tends to increase.

To perform the hypothesis test we compare the p-value to the chosen significance level (typically 0.05). The p-value represents the probability of obtaining a correlation coefficient as extreme as the observed value (or more extreme) if the null hypothesis were true (rho = 0). If the p-value is smaller than the significance level, we reject the null hypothesis in favor of the alternative hypothesis, indicating that there is a significant correlation.

In this case, the p-value is less than 0.05, which means the probability of observing a correlation coefficient as extreme as 0.926 (or more extreme) under the assumption of no correlation is very low. Therefore, we reject the null hypothesis and conclude that there is a non-zero correlation between temperature and plant growth.

Note: The provided equation "y cap = 1.905x + 5.055" and the value "sigma(Z_x middot Z_y) = 8.875" are not directly used in calculating the correlation coefficient or performing the hypothesis test. They may be additional information given for the purpose of further analysis or calculations.
