Answer:
The probability that the proportion of flops in a sample of 442 released films would differ from the population proportion by greater than 4% is:
= 0.094
= 9.4%
Step-by-step Explanation:
Estimated probability that the films released are flops = 9%
Sample of released films = 442
Estimated number of flops = 39.78 (442 * 9%)
If the population proportion of flops will be greater by 4%,
Therefore, the number of flops will increase to 41.37 (39.78 * 1.04)
This gives a new proportion of flops as 0.0936 (41.37/442)
Answer:
18 cups of lemonade
Step-by-step explanation:
so if it cost him $0.15 to make each cup of lemonade and he sold a cup for $0.35 then he sold 18 cups
in right angle traingle two angle are equal
so.x=y
in triangle
x+y+90=180(sum of interior angle of triangle)
2x=180-90
x=90/3=45°
I’m not gonna lie. I’m just answering so I could upload my question
Ducks have 1 head. Dogs have 1 head.
Ducks have 2 feet. Dogs have 4 feet.
If x = no. of ducks and g = no. of dogs
x + g = 25
2x + 4g = 80
Let's use substitution to solve.
x + g = 25 ⇒ x = 25 - g
replace x with 25 - g in the other equation and solve for g
2x + 4g = 80
2(25 - g) + 4g = 80
50 - 2g + 4g = 80
50 + 2g = 80
2g = 30
g = 15
Now use g = 15 in an earlier equation to find x.
x + g = 25
x + 15 = 25
x = 10
