An angle is made up of 66 one-degree angles. What is the measure of the angle?
Answer:
66 degrees
Step-by-step explanation:
if there are 66 one degree angles, all alll those together to get 66 degrees in total
The measure of the angle that is given with the given parameter is; 66°
How to find the value of the angle?
We are told that ang angle is made up of 66 one-degree angles. Now, this means that each of the section of the main angle is one degree.
Thus, the value of 66 numbers of that angle will be;
66 * 1 = 66°
In conclusion, the measure of the angle is 66°.

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 8.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 250 engines and the mean pressure was 8.1 pounds/square inch. Assume the variance is known to be 1.00. A level of significance of 0.01 will be used. Make a decision to reject or fail to reject the null hypothesis. Make a decision
Answer:
The calculated value z= 0.0063 does not fall in the critical region so we fail to reject the null hypothesis. And accept that the valve does not perform above the specifications.
Step-by-step explanation:
Given that
Population mean= μ = 8.0
Sample mean= x`= 8.1
Sample size= n= 250
Sample standard deviation= s= 1.00
Significance level= ∝ =0.01
The null hypothesis and alternate hypothesis are
H0: μ < 8.0
Ha: μ ≥ 8.0 One tailed test
The claim is that the valve perform above the specifications
The critical value at 0.01 significance level for one tailed test is z > ±2.33
The test statistic z is used
z= x`- μ/ σ/√n
Z= 8.1-8.0/ 1/√250
z= 0.1/1/15.811
z= 0.0063
The calculated value z= 0.0063 does not fall in the critical region so we fail to reject the null hypothesis.

How many solutions does this system of linear equations have? Explain.
1= 2
=1+3 2
Answer: There are no real solutions.
Step-by-step explanation:
We have the equation:
x = y^2
y = x + 3/2
To solve this, we can start by noticing that x is already isolated in the first equation, then we can replace it in the second equation to get:
y = y^2 + 3/2
And now we can rewrite this as:
y^2 - y + 3/2 = 0
This is a quadratic equation, and the solutions can be calculated with Bhaskara's equation, the solutions are:
[tex]y = \frac{-(-1) +- \sqrt{(-1)^2 - 4*3/2*1} }{2*1} = \frac{1 + \sqrt{-5} }{2}[/tex]
We have a negative number inside the square root, this means that the solutions are complex numbers.
Then we can conclude that the system of equations has no real solutions.
Huong is organizing paperback and hardback books for her club’s used book sale. The number of paperbacks is 12 less than three times the number of hardbacks. Huong had 162 paperbacks. How many hardback books were there?
Answer:
There were 58 hardback books there.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of paperback books.
y is the number of hardback books.
The number of paperbacks is 12 less than three times the number of hardbacks.
This means that:
[tex]x = 3y - 12[/tex]
Huong had 162 paperbacks.
This means that [tex]x = 162[/tex]
How many hardback books were there?
We want to find y.
So, using the value of x, and the first equation, we have that:
[tex]x = 3y - 12[/tex]
[tex]3y = x + 12[/tex]
[tex]3y = 162 + 12[/tex]
[tex]3y = 174[/tex]
[tex]y = \frac{174}{3}[/tex]
[tex]y = 58[/tex]
There were 58 hardback books there.

Your team wins 24 medals at a competition. The medals are gold, silver, and bronze in a ratio of 1:1:6. How many of each medal did your team win?
gold
Answer:
3 gold
3 silver
18 bronze
Step-by-step explanation:
Look at the ratio. 1:1:6. Add the numbers together and you get 8 right?
8 × 3 = 24
Now that you know how much to multiply each part of the ratio by, (3, if you didn't get that.) now you multiply.
1 × 3 = 3 Gold
1 × 3 = 3 Silver
6 × 3 = 18 Bronze

finding the slope (simplest form)
Answer:
m=3, y = 3x - 2
Step-by-step explanation:
slope = rise / run
slope = 6/2
slope = 3
Answer:
The slope is 3.
Step-by-step explanation:
Slope is equal to rise over run. Let’s take a look at the points given to us on the graph.
To go from the leftmost point to the rightmost point, we rise (go up) 6 units, and then we run over (go right) 2 units. So we have:
Slope = Rise/run = 6/2
Now 6/2 is equal to 3, and that’s the slope.

The quadratic regression function for the given data function can be written as f(x) = 2.55357143 + 52.8875x - 15.97519841x².
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that during one game, the Dallas Cowboys punter was called upon to punt the ball eight times. On one of these punts, the punter struck the ball at his own 30-yard line. The height {h} of the ball above the field as a function of time {t} in seconds can be partially modeled by the following table -
{t} 0 0.6 1.2 1.8 2.4 3.0
h{t} 2.50 28.56 43.10 46.12 37.12 17.60
Using the graphing calculator, we can calculate the values as -
Mean of {x} : 1.5
Mean of {y} : 29.16666667
Correlation coefficient {r} : 0.9999376942
A : 2.55357143
B : 52.8875
C : -15.97519841
We can write the quadratic regression function as -
f(x) = A + Bx + Cx²
f(x) = 2.55357143 + 52.8875x - 15.97519841x²
Therefore, the quadratic regression function for the given data function can be written as f(x) = 2.55357143 + 52.8875x - 15.97519841x².

Answer:
10
Step-by-step explanation:
Let us find the exact number of donors of gold and bronze respectively given there are 40 in total.
Gold: 45% of 40 = 45/100 *40 = 18 donors
Bronze: 20% of 40 = 20/100 *40 = 8 donors
18 donors - 8 donors = 10 more donors
