An SRS of size 20 is drawn from a population that has a normal distribution. The sample has a mean of 122.5 and a standard devia

Tems11 [23]

Answer:

The value is $\sigma_{\= x} = 1.789$

Step-by-step explanation:

From the question we are told that

The sample size is n = 20

The sample mean is $\= x = 122.5$

The standard deviation is $s = 8$

Generally the standard error of the mean is mathematically represented as

$\sigma_{\= x} = \frac{s}{\sqrt{n} }$

=> $\sigma_{\= x} = \frac{8}{\sqrt{20 } }$

=> $\sigma_{\= x} = 1.789$

A. x-int:-0.5,y-int:1 B. x-int:0.5,y-int:1 C. x-int:-0.5,y-int:-1 D. x-int:1,y-int:0.5

hodyreva [135]

The correct answer is: [D]: " x-int : 1 , y-int: 0.5 " .

The "x-intercept" refers to the point(s) at which the the graph of a function (which is a "line", in this case) cross(es) the "y-axis".

In other words, what is (are) the point(s) of the graph at which "x = 0" ?

By examining the graph, we see that when " x = 0" ; y is equal to: "1" .

So; the "x-intercept" is at point: "(0, 1)" ; or, we can simply say that the
"x-intercept" is: "1" .

Shane wants to plant 28 marigold plants and 36 rose plants in his garden. What is the greatest number of rows possible if each r

Dennis_Churaev [7]

Answer:

HCF=2*2=4

Step-by-step explanation:

Given : Shane wants to plant 28 marigold plants and 36 rose plants in his garden

To Find : the greatest number of rows possible each row has the same

number of marigold plants and the same number of rose plants.

Solution:

marigold plants = 28

rose plants = 36

To find the greatest number of rows possible if each row has the same

number of marigold plants and the same number of rose plants.

we need to find HCF of 28 and 36

28 = 2 x 2 x 7

36 = 2 x 2 x 3 x 3

HCF = 2 x 2 = 4

greatest number of rows possible is 4
