Answer:

93 square metres

Step-by-step explanation

The formula for surface area is 2ab+2ac+2bc, and with no lid one bc can be removed.

Suppose a=7 b=3 and c=3

2(7x3)+2(7x3)+(3x3)=93

A spinner contains the numbers 1 through 50. What is the probability that the spinner will land on a number that is not a multip

ASHA 777 [7]

Answer:

The answer is 24.

Step-by-step explanation:

from 0 to 50 there are 12 numbers that are a multiple of 4 now we convert the 12 and 50 into a fraction it would look like this:

12/50

then we need to find the least common denominator of 50 and 100, it is 100 so we multiply 50 and 12 times 2 to get an answer of 24/100.

Consider random samples of size 50 from a population with proportion 0.15

WITCHER [35]

Answer:

a) Mean = 0.75

b) Standard error = 0.051

c) Yes

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Sample proportion , p = 0.15

a) Mean

$\mu = np = 50(0.15) = 7.5$

b) Standard error

$S.E = \sqrt{\dfrac{p(1-p)}{n}} = \sqrt{\dfrac{0.15(1-0.15)}{50}} = 0.051$

c) Application of central limit theorem

Since the sample size is larger than 30, we cam apply central limit theorem for normal approximation.
