Answer:
C = 5/9 (F - 32)
This is a temperature scale change comparison.
By this we understand, that ,
1°C = 5/9°F
Which is equal to, 5/9°F = 1°C
These two statements are satisfied by I. and II.
So, the correct answers are, I. and II.

Answer:
p = 23
q = 18
Step-by-step explanation:
The four interior angles of a square are all 90° each
4p - 2 = 90
⇒ 4p = 92
⇒ p = 92 ÷ 4
⇒ p = 23
5q = 90
⇒ q = 90 ÷ 5
⇒ q = 18
Answer:
p=23; q=18.
Step-by-step explanation:
1) m∠(XWZ)=90, then 4p-2=90 and p=23°;
2) m∠(WZY)=90, then 5q=90 and q=18°.

The value of x that will make the considered parallelogram ABCD a rhombus is 4 units.
What is rhombus and some of its properties?Rhombus is a parallelogram whose all sides are of equal lengths.
Its diagonals are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).Its vertex angles are bisected by its diagonals.The triangles on either side of the diagonals are isosceles and congruent.For this problem, the missing figure is attached below.
We see that the angle between the diagonals is [tex](3x- 12)^\circ[/tex]
It is given that ABCD is a parallelogram.
For ABCD parallelogram to be a rhombus, its diagonals need to be perpendicular to each other.
Perpendicular lines have 90° angle between them.
Thus, we need:
[tex](3x- 12)^\circ = 90^\circ[/tex]
Evaluating value of x:
[tex](3x- 12)^\circ = 90^\circ\\3x - 12 = 90\\\text{Adding 12 on both the sides}\\3x = 102\\\text{Dividing both the sides by 3}\\\\x = 12/3 = 4[/tex]
Thus, the value of x is 4

Which situation can be represented by the inequality x < 56? A) Tina's dog weighed 56 pounds two months ago. He gained weight and weighs x pounds now. B) Tina has x dollars. She has more than enough money to buy a camera that costs $56. C) Tina walks for 56 minutes. She walks for the same amount of time as her sister, who walks for x minutes. D) Tina's height is x inches. She is shorter than her brother, whose height is 56 inches.
Given:
The inequality is [tex]x<56[/tex].
To find:
The correct situation for the given inequality.
Solution:
Tina's dog weighed 56 pounds two months ago. He gained weight and weighs x pounds now. It means, weighs x pounds is more than 56 pounds.
[tex]x>56[/tex]
So, option A is incorrect.
Tina has x dollars. She has more than enough money to buy a camera that costs $56. It means, amount $x is more than required amount $56.
[tex]x>56[/tex]
So, option B is incorrect.
Tina walks for 56 minutes. She walks for the same amount of time as her sister, who walks for x minutes. It means, x is equal to 56.
[tex]x=56[/tex]
So, option C is incorrect.
Tina's height is x inches. She is shorter than her brother, whose height is 56 inches. It means, Tina's height is x inches is less than her brother's height, i.e., 56 inches.
[tex]x<56[/tex]
Therefore, the correct option is D.

Write an equation of the line passing through (-4,7) and having slope - 5. Give the answer in slope-intercept form.
The equation of the line in slope-intercept form is
Answer:
Step-by-step explanation:
The general equation is y = mx + b
You already have m which is the slope. So the general equation becomes y = -5x + b
The point is meant to find b
x = - 4
y = 7
7 = - 5*-4 + b
7 = 20 + b Subtract 20 from both sides.
7 - 20 = 20-20 + b Combine
- 13 = b
Answer: y = - 5x - 13

A z-table is also known as the standard normal distribution table. The probability of P(0.75≤ z ≤ 1.25) is 0.121.
What is a Z-table?A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.
As it is given that the probability and the z-table is given to us, as shown below,
z Probability
0.00 0.5000
0.25 0.59871
0.50 0.6915
0.75 0.7734
1.00 0.8413
1.25 0.8944
1.50 0.9332
1.75 0.9599
The following probabilities can be written as:
1. The probability of P(-1.25)
[tex]P(-z)=1-P(z)\\\\P(-1.25)=1-P(1.25)\\\\P(-1.25)=1-(0.8944)\\\\P(-1.25)=0.1056[/tex]
The probability of P(-1.25) is 0.1056.
2. The probability of P(-1.25 ≤ z ≤ 0.25)
[tex]P(-1.25\leq z\leq 0.25)=P(0.25)-P(-1.25)\\\\P(-1.25\leq z\leq 0.25)=0.59871-0.1056=0.49311[/tex]
The probability of P(-1.25 ≤ z ≤ 0.25) is 0.49311.
3. The probability of P(-1.25 ≤ z ≤ 0.75)
[tex]P(-1.25\leq z\leq 0.75)=P(0.75)-P(-1.25)\\\\P(-1.25\leq z\leq 0.75)=0.7734-0.1056=0.6678[/tex]
The probability of P(-1.25 ≤ z ≤ 0.75) is 0.6678.
4. The probability of P(0.25 ≤ z ≤ 1.25)
[tex]P(0.25 \leq z\leq 1.25)=P(1.25)-P(0.25)\\\\P(0.25\leq z\leq 1.25)=0.8944-0.59871=0.29569[/tex]
The probability of P(0.25 ≤ z ≤ 1.25) is 0.29569.
5. The probability of P(0.75≤ z ≤ 1.25)
[tex]P(0.75\leq z\leq 1.25)=P(1.25)-P(0.75)\\\\P(0.75\leq z\leq 1.25)=0.8944-0.7734=0.121[/tex]
The probability of P(0.75≤ z ≤ 1.25) is 0.121.

18 hours after 10 AM
Step-by-step explanation:
We are looking for the time the helicopter and the plane will be the same distance from Burbank after 10 AM.We are given the two equations for the distance that the helicopter and the plane are away, in miles.It also says that R is the variable for time.Using this information, we need to solve for the time with broth equations, so we would set both up to be equal to each other, since they will be the same distance away from each other.It would look like this: -150r + 260 = -270r + 440.Add 150r to both sides.260 = -10r + 440.Add -10r to both sides.Now we have 10r + 260 = 440Subtract 260 from both sides.10r = 180Divide each side by 10 to isolate the R.R = 18.It would be 18 hours after 10 AM.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

The are of a circle is 109.4cm^2. Calculate the length of its radius.
Answer:
r≈ 5.9 cm
Step-by-step explanation:
A study investigated the job satisfaction of teachers allowed to choose supplementary curriculum for their classes versus teachers who were assigned all curricular resources for use in their classes. the authors of the study wanted to know if the two groups of teachers had different levels of job satisfaction. they will use a significance level of 5% for their test. upper-tail values a 5% 2.5% 1% critical z-values 1.65 1.96 2.58 what is (are) the critical value(s) for z in this study? –1.65 and 1.65 –1.96 and 1.96 1.65 1.96
The critical values of Z in this study are given by: Option C: -1.96 and 1.96
How to form the hypotheses?There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test. The hypothesis which we put against null hypothesis is alternate hypothesis.
Null hypothesis is the one which researchers try to disprove.
For this case, we want to know if the two groups of teachers had different levels of job satisfaction.
Suppose that we have:
[tex]\mu_1[/tex] = mean of level of job satisfaction for first group of teachers.[tex]\mu_2[/tex] = mean of level of job satisfaction for second group of teachers.Then, as the test is for checking if the difference exist, the null hypothesis will deny existence of any difference.
Thus, we get:
Null hypothesis: [tex]H_0: \mu_1-\mu_2 = 0[/tex] or we say [tex]H_0: \mu_1 = \mu_2[/tex]Alternate hypothesis: [tex]H_1: \mu_1-\mu_2 \neq 0[/tex] or we say [tex]H_1: \mu_1 \neq \mu_2[/tex]The alternate hypothesis creates two regions, on either side as:
[tex]\mu_1 < \mu_2[/tex] and [tex]\mu_1 > \mu_2[/tex]
This is why it is two tailed test.
The level of significance is 5% specified.
Thus, [tex]\alpha = 5\% = 5/100 = 0.05[/tex]
From the critical values table, the critical value(s) of Z for level of significance 0.05 and for two tailed test are: [tex]\pm 1.96[/tex]
Thus, the critical values of Z in this study are given by: Option C: -1.96 and 1.96
