Answer:
2 1/2 or 5/2 cups of milk
Step-by-step explanation:
if 16 cookies are made from 1 2/3 cups of milk which equals 5/3 cups of milk that means that you need 5/2 or 2 1/2 cups of milk to make 24 cookies because you need to multiply 5/3 by 16 and then multiply 5/48 by 24 which is 5/2 or 2 1/2 cups of milk

which of the following graph represents the solution set for 5x+38 ≤ 4(2-5x)
Answer:
Option C
Step-by-step explanation:
Given inequality is,
5x + 38 ≤ 4(2 - 5x)
5x + 38 ≤ 8 - 20x [Distributive property]
5x + 20x + 38 ≤ 8 - 20x + 20x [By adding 20x on both the sides of the inequality]
25x + 38 ≤ 8
(25x + 38) - 38 ≤ 8 - 38 [By subtracting 38 on both the sides of the inequality]
25x ≤ -30
[tex]\frac{25x}{25}\leq -\frac{30}{25}[/tex] [Dividing by 25 on both the sides of the inequality]
x ≤ 1.2
Therefore, Option (C) will be the correct graph.
Can anyone solve this? If so tell me and make sure u know what ur doing please
Answer:
-2
Step-by-step explanation:
To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).
[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]
= [tex]\frac{-2-2}{-1+3}[/tex]
= [tex]\frac{-4}{2}[/tex]

The difference between teenage female and male depression rates estimated from two samples is 0.08. The estimated standard error of the sampling distribution is 0.04. what is the 95% confidence interval? Use the critical value z - 1.96.
Round all calculations to two decimal places. Put lower bound in the first box and upper bound in the second box.
Answer: (0.0016, 0.1584)
Step-by-step explanation:
Given that:
Mean (m) = 0.08
Standard Error = 0.04
Zcritical at 95% = 1.96
Using the relation :
Mean ± Zcritical * (standard error)
0.08 ± 1.96 * (0.04)
Lower boundary = 0.08 - (1.96 * 0.04)
Lower boundary = 0.08 - 0.0784 = 0.0016
Upper boundary = 0.08 + (1.96 * 0.04)
Upper boundary = 0.08 + 0.0784 = 0.1584
Confidence interval is Hence,
(0.0016, 0.1584)
The 95% confidence interval is given by (0.0016 , 0.1584) and this can be evaluated by using the mean and standard error relation.
Given :
The difference between teenage female and male depression rates estimated from the two samples is 0.08.The estimated standard error of the sampling distribution is 0.04.The critical value z = 1.96.95% confidence level.To determine the 95% confidence interval using the following relation:
[tex]\rm \mu \pm z_{critical}\times standard \;error[/tex]
[tex]0.08\pm 1.96\times 0.04[/tex]
So, the lower and upper boundary is (0.0016 , 0.1584).
Therefore, the 95% confidence interval is given by (0.0016 , 0.1584).

Carl is the beneficiary of a $29,000 trust fund set up for him by his grandparents. Under the terms of the trust, he is to receive the money over a 7-year period in equal installments at the end of each year. If the fund earns interest at the rate of 4%/year compounded annually, what amount will he receive each year?
Answer:
$8,939.58
Step-by-step explanation:
Let x represent the amount to be received each year
==> x * Present value annuity factor (4%,7yrs) = $29,000
==> x * 3.240 = $29,000
==> x = $29,000/3.244
x = 8939.580764488286
x = $8,939.58
So, $8,939.58 is the amount he will receive each year.
