Answer:

Sample size should be less than 85

Step-by-step explanation:

Sample size should be less than 85

Step-by-step explanation:

To use the infinite standard deviation formula, n has to be <= (0.05)(1700)

n <= 85

So the sample size has to be less than 85

In another way too,

n = sample size

N = population size

For population, we multiply correction factor to the infinite standard deviation

F is <= 0.05

n/{N}

n<0.05x1700

n<85

Sample size should be less than 85

(Multiying by a unit fraction. Find the product mentally. (5.6) × 1/8=
Ipatiy [6.2K]

Step-by-step explanation:

(5.6) × 1/8

(5.6)  \cdot   \frac{1}{8}

Here the unit fraction is 1/8

multiply 5.6 times 1

so its 5.6. then divide the decimal by 8

we know that 8 times 7 is 56

so 56 divide by 8 is 7

we have decimal point 1 number to the left

so we move decimal point 2 place left

Hence 5.6 divide by 8 is 0.7

(5.6)  \cdot   \frac{1}{8}=0.7

Answer: 0.7

IgorC [24]

Answer:

21.6 or 22

Step-by-step explanation:

Triangles have same angles. This means that they are proportion.

50/27 = 40/x

when you cross multiply to solve x, 50x = 1080

so x = 21.6

If you have to nearest whole number, it will be 22

Indicate whether the following statements are True (T) or False (F).
chubhunter [2.5K]
1.  False because a rational is a fraction or part of a number (\frac{3}{2}, 3.2).  \sqrt{49} = 7

2.  True; a real number is any number that isn't imaginary (i, \sqrt{-1})

3.  True; same reason

4.  True; an integer is any number that can be wrote without a fraction or decimal (the opposite of rational).

5.  True; \sqrt{3} \approx 1.32 and that's a decimal.

6.  True;  the natural number system starts from 0 and counts upwards

7.  True;  reason above
