8x.65= 5.2 I haven’t learned this but I’m trying my best to or maybe it will be 8+.65 which will be 8.65 which is close to 9

Calculate the sum of 1/4 and 1/7

KonstantinChe [14]

Try to find the lowest common denominator. In this case it's 28, which makes our numbers as follows:

1/4 = 7/28
1/7 = 4/28

7/28 + 4/28 = 11/28

We can't simplify it so that's the result.

A population is normally distributed with mean 18 and standard deviation 1.7. (a) Find the intervals representing one, two, and

elena55 [62]

Answer:

Interval within 1 standard deviation: (16.3,19.7)

Interval within 2 standard deviation: (14.6, 21.4)

Interval within 3 standard deviation: (12.9, 23.1)

Step-by-step explanation:

We are given the following in the question:

Population mean, $\mu$ = 18

Standard deviation, $\sigma$ = 1.7

We have to find the following intervals:

Interval within 1 standard deviation:

$\mu \pm 1\sigma\\=18 \pm 1.7\\=(16.3, 19.7)$

Interval within 2 standard deviation:

$\mu \pm 2\sigma\\=18 \pm 2(1.7)\\= 18 \pm 3.4\\=(14.6,21.4)$

Interval within 3 standard deviation:

$\mu \pm 3\sigma\\=18 \pm 2(1.7)\\= 18 \pm 5.1\\=(12.9,23.1)$

Answer:

16

Step-by-step explanation:

4/5 X 20

therefore: we will first multiply 4 X 20 and get 80

Therefore: we will then divide by 5 and get 80/5 = 16

PS: If anyone can teach me latex on this source please do and also does it even work.
