Answer:
19
Step-by-step explanation:
Difference between one end point and mid point
= 27 - 23 = 4
Other endpoint = 23 - 4 = 19
After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?
Answer:
D
Step-by-step explanation:
The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

Thanks for your time! Have good day!Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310
Answer:
[tex]60c + 85s \geqslant 310[/tex]
Step-by-step explanation:
He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.
The required inequality:
60x + 85y >= 310
What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given, a person gets paid $60 to detail a car and $85 to detail an SUV.
Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.
Then, the amount earned by detailing x cars and y SUVs can be expressed as:
60x + 85y
According to the problem statement, he wants to earn at least $310, so we can write the inequality:
60x + 85y >= 310
This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.

3. What is the sum of the interior angles of a polygon with 32 sides?
Answer:
Step-by-step explanation:
To find the sum of an interior angle of a polygon, you have to follow these steps:
Interior angle= ( n - 2 ) ×180° all over n
So interior = ( 32 - 2 ) × 180° all over 32
Interior = 30 × 180 all over 32
Therefore your interior angle should be 168.75°

is -27 divided by (-3) positive or negative & how
Answer:
It is positive (9)
Step-by-step explanation:
Negative ÷ negative = positive
Negative ÷ positive = negative
positive ÷ positive = positive
positive ÷ negative = negative
Negative × negative = positive
negative × positive = negative
positive × positive = positive
Positive × negative = negative
If both symbols are the same, it is positive. If one is positive and one is negative (different symbols), it is negative.
The result is 9. Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.
When dividing -27 by -3, the result is positive. In this case, the negative signs cancel out each other, and two negatives make a positive.
To understand why, think of division as the process of finding out how many times one number (divisor) can fit into another number (dividend). In this case, we are trying to find out how many times -3 can fit into -27.
-27 ÷ (-3) = 9
Here's the step-by-step calculation: -3 times 9 equals -27, which matches the dividend. So, the result is 9.
Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.
In conclusion, -27 divided by -3 is positive 9.

Answer:
f(5) = -11
Step-by-step explanation:
Given that,
f(x) = 4-3x ....(1)
We need to find the value of f(5).
Put x = 5 in equation (1)
f(5) = 4-3(5)
= 4-15
= -11
So, the value of f(5) is equal to -11.

You purchase a video game system for $150. You make a down payment of $25. You pay the rest of the money you owe in 5 equal monthly payments with no interest. How much is each monthly payment ?
Can you help me set the problem up too? thx
9514 1404 393
Answer:
$25
Step-by-step explanation:
Let p represent the monthly payment. There are 5 of them, so the amount of their total is 5p. That, together with the down payment, makes up the entire cost of the system.
5p +25 = 150 . . . . an equation representing the relationships
__
To solve this, subtract 25 and divide by 5.
5p = 125
p = 125/5 = 25
Each monthly payment is $25.
Help me pleasee. Solve the system by substitution
Answer:
(3, - 2 )
Step-by-step explanation:
Given the 2 equations
4x - 2y = 16 → (1)
y = - 5x + 13 → (2)
Substitute y = - 5x + 13 into (1)
4x - 2(- 5x + 13) = 16 ← distribute and simplify left side
4x + 10x - 26 = 16
14x - 26 = 16 ( add 26 to both sides )
14x = 42 ( divide both sides by 14 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 5(3) + 13 = - 15 + 13 = - 2
solution is (3, - 2 )
