Answer:

C

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:

C) A random sample of 10 taken from a population distribution that is skewed to the right

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.

Answer:

b

Step-by-step explanation:

The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.

A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.

B. (55, 10), so 55/10=5.5.

C. (20, 4), so 20/4=5.

D. (50, 10), so 50/10=5.

Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.

The total number of students in the survey is 110 students.

Given that, in a survey of students, every student studies at least one of the three subjects Maths English and Science

A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.

Let Math=M, Science=S and English=E

n(M)+n(S)+n(E)=1/2 (n(M∩S)+n(S∩E)+n(E∩M)

Let the number of students who study only one subject be x.

Let the number of students who study only two subjects be x/2.

n(M∩S∩E)=20

n(M∩S)+n(S∩E)+n(E∩M)=80

∪=x/2+80

∪=x+ x/2+20

Now, x/2+80 = x+ x/2+20

⇒ x=60

So, ∪=x/2+80 =110

Therefore, the total number of students in the survey is 110 students.

Answer:

  $2000

Step-by-step explanation:

The amount of interest is given by the formula ...

  I = Prt

where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.

  50 = P(0.05)(1/2)

  P = 50/(0.05·1/2) = 2000

Answer:

$13.50

Step-by-step explanation:

Hardcover Books = $18.25 each

Softcover Books = $5 each

She bought 2 hardcover and 2 softcover.

Hardcover: $18.25 + $18.25 = $36.50

We already know what 2 softcover books cost ($10)

No add those both together.

$36.50 + $10.00 = $46.50

She gives the clerk $60

$20 + $20 = 40

$20 + $20 = 40

$20 - $6.50 = $13.50

Answer:

Gateway Arch is [tex]292.46[/tex] feet tall

Step-by-step explanation:

As we know,

the horizontal distance from the gate of the Arch to the bench [tex]= 724[/tex] feet

The angle of elevation is [tex]22[/tex] degree

Let H be the height of the gate be "H"

Tanθ= Perpendicular/Base

Substituting the given values in above equation, we get -

[tex]tan 22 = \frac{H}{724} \\H = 724 * tan 22\\H = 724 * 0.404\\H = 292.46[/tex]feet

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {c}^{2} - {b}^{2} = {a}^{2} [/tex]

[tex] {20}^{2} - {11}^{2} = {279}^{2} [/tex]

[tex] \sqrt{279} = 16.7 \: inches[/tex]

Length of the the other leg in the right triangle is 16.7 inches

A triangle in which one of the interior angles is 90° is called a right triangle

Length of the one leg = 11 inches

Hypotenuse = 20 inches

Plot the figure using the given data

From the figure

[tex]AC^{2}=AB^{2}+BC^{2} \\BC=\sqrt{AC^{2}-AB^{2} } \\BC=\sqrt{20^{2}-11^{2} } \\BC=\sqrt{400-121} \\BC=\sqrt{279}[/tex]

BC= 16.7 inches

Hence, the length of the other leg is 16.7 inches
