Answer:
number 1 is 2 number 2 is 15 number 4 is 30
Step-by-step explanation:
Answer:
the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5.
Step-by-step explanation:
According to the Central Limit Theorem, assuming the sampling is random and sample size is big enough (≥30) the mean of the sampling distribution is the population mean.
Therefore the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5
To find the average of numbers you have to add all the numbers and divide by the number of numbers. *confusing*
25 + 25.4 + 25.35 + 26.1 = 101.85
101.85 ÷ 4 = 25.4625

In left one)
the 3 angles are equal so the sides are equal then we can say
then x is 30÷11
the right one) is exactly similar
Formula for perimeter of a rectangle: P = 2W + 2L
Here, P = 2(x-3 ) cm + 2(3x+7) cm = 2x - 6 + 6x + 14 (cm)
Combine like terms: 8x + 8 cm (simplest form) This is the perimeter.
Now let x = 4: P(x=4) = 8(4) + 8 cm = 40 cm
