Keisha is babysitting at $8 per hour to earn money for a car. So far she has saved $1300. The car that Keisha wants to buy costs at least $5440. Write and solve an inequality to determine the amount Keisha still needs to earn for the car.
Answer:
$4100
Step-by-step explanation:
For Kaisha to get this car we have these information available
Amount saved = $1300
The cost of the car = $5400
Let The amount left to complete the car = k
We have this equation
K + $1300 = $5400
K = 5400 - 1300
K = 4100
Therefore Kaisha still needs to earn an additional amount of $4100 for the total amount of the car to be completed.

The population of a village is in the following ratios.
women: children = 13:4
men: children = 7:3
a) Find the ratio women : men.
Give your answer in its simplest form.
women : men
Answer:
13:7
Step-by-step explanation:
We see that the ratio from women:children is 13:4.
Therefore, the number of women is 13.
In the ratio comparing men to children we see that it is 7:3.
Therefore, the number of men is 7.
Now we need to compare the number of women to the number of men which is 13:7.

a profit of 24% was made wheb a book was sold for birr 34% find the selling price that would have given a profit 28%
Answer:
$35.20
Step-by-step explanation:
Given that the profit of 24% was made on $34.10,
And Profit = Selling price - cost price,
Where profit is 24%, and selling price is $34.10, cost price = ?
Then, to find the cost price (z):
Assume the cost price be a 100% and the selling price of $34.10 be 124%
Hence, we have
$34.10 = 124%
z = 100%
Substitue
=> z / 34.10 = 100% / 124 %
=> 124z = 34.10 (100)
124z = 3410
Divide both sides by the coefficient of z which is 124
z = $27.50
Therefore, to find the selling price for a profit of 28%
We have 28% of 27.5 = 7.70
With equation of Profit = Selling price - cost price
We have 7.70 = Selling price - 27.50
Removing 7.7 from both sides
We have, Selling price = 27.50 + 7.70
=> Selling price = $35.20
Hence, the selling prices for a profit of 28% is $35.20
Assume that a simple random sample has been selected and test the given claim.Claim: The average age of actresses when they win an acting award is more than 34 years oldTo test this claim a simple random sample (SRS) of 27 actresses is used. This sample of 27 actresses had a sample mean of 31.4 years and a standard deviation = 11.2 years. Assume the the distribution of actresses ages is approximately normal.Select all TRUE statements from those given below..For this hypothesis test; H0: ? 34 H1: ?>342. The correct decision is to "support" (fail to reject) the null hypothesis H0.3. We decide to reject the claim that the average age of actresses when they win an acting award is more than 34 years old.4. For this hypothesis test, the P-value = .8815. For this hypothesis test, the test statistic is t = -1.21

O A. y = -0.59x + 12.5
B. y = 0.30x2 + 0.48x + 15.83
C. y = 12.00 0.94%
Answer:
a will be the correct answer bro be sure
The Regression equation best fits these data is ŷ = -0.58939x + 12.52235
We have the table as from which can be calculated as
Sum of X = 2
Sum of Y = 99
Mean X = 0.25
Mean Y = 12.375
Sum of squares (S[tex]S_x[/tex]) = 89.5
Sum of products (SP) = -52.75
As, Regression Equation
ŷ = b x + a
where b = SP/S[tex]S_x[/tex]
b = -52.75/89.5
b = -0.58939
and, a = MY - b MX
a = 12.38 - (-0.59)(0.25)
a = 12.52235
So, the required equation is ŷ = -0.58939x + 12.52235
