Answer:

11/12

Step-by-step explanation:

::::::::::::::::

The probability of the number on the upward face is not 4 would be 11/12 or 0.92 by calculating as follows:

Solution:

The possible outcomes for rolling a dodecahedral die, numbered from 1 to 12, once is given below in the term of sample space S:

S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

Therefore,

n(S) = 12

Event A: Sample space in the case of not having number 4 on the upward face:

A = {1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12}

therefore,

n(A) = 11

the required probability = [tex]\dfrac{\text{Number of times event A, occurred}}{\text{Number of times this experiment performed}}[/tex]

then putting the space values here;

 = [tex]\frac{n(A)}{n(S)}=\frac{11}{12}=0.92[/tex]

Thus, the required probability is 0.92

I can't plot it for you, but the slope will be the y/x or the rise/run.

You can find the slope by using 2 points of the line and subtracting the (y1-y2)/(x2-x1)

Answer:

The pvalue of the test is 0.7188 > 0.05, which means that there is not enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research.

Step-by-step explanation:

Test if there is enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research:

This means that at the null hypothesis we test if the proportion is 62%, that is:

[tex]H_0: p = 0.62[/tex]

At the alternate hypothesis, we test if the proportion is different from 0.62, that is:

[tex]H_a: p \neq 0.62[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample

62% is tested at the null hypothesis:

This means that [tex]\mu = 0.62, \sigma = \sqrt{0.62*0.38}[/tex]

When a random sample of 26 autistic children were observed, 17 were found to be left-handed.

This means that [tex]n = 26, X = \frac{17}{26} = 0.6538[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.6538 - 0.62}{\frac{\sqrt{0.62*0.38}}{\sqrt{26}}}[/tex]

[tex]z = 0.36[/tex]

Pvalue of test and decision:

The pvalue of the test is the probability of a proportion that differs from the mean by at least 0.6538 - 0.62 = 0.0338, which is P(|z| > 0.36), which is two multiplied by the pvalue of z = -0.36

Looking at the z-table, z = -0.36 has a pvalue of 0.3594

2*0.3594 = 0.7188

The pvalue of the test is 0.7188 > 0.05, which means that there is not enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research.

Answer:

x is about 0.26

Step-by-step explanation:

[tex]e^{4-7x}+11=20[/tex]

[tex]e^{4-7x}=9[/tex]

[tex]ln(e^{4-7x})=ln(9)[/tex]

[tex]4-7x=ln(9)[/tex]

[tex]-7x=ln(9)-4[/tex]

[tex]x=\frac{ln(9)}{-7} +\frac{4}{7}[/tex]

[tex]x=\frac{4-ln(9)}{7}[/tex]

[tex]x=0.2575393461[/tex]

Answer:

Q = 12 meters

Step-by-step explanation:

Since all angles of the triangles are the same, the two triangles are similar. Therefore, all you need to do is a simple comparison equation like 10/15=8/x and solve.

Cross multiply, 10x=120. Divide and get x = 12.

Hope this helps!

Answer:

Step-by-step explanation:

since we know that triangles have 180° we know that 116° is two much if it's doubled  2*116 = 232° so that angle has to be the single angle and the left over of 180 - 116  is the left over amount that is even divided into the last two angles so   180 - 116 = 64 / 2 = 32°  so the triangle is made up of  116 + 32 + 32 degree angles

9514 1404 393Answer:

  20, 36

Step-by-step explanation:

Let x and y represent the smaller and larger numbers, respectively. The given relations let us write two equations:

  x + y = 56 . . . . . . the sum of the two numbers is 56

  2x -y/2 = 22 . . . . twice the smaller exceeds half the larger by 22

We can solve this by multiplying the second equation by 2 and adding the first.

  2(2x -y/2) +(x +y) = 2(22) +56

  5x = 100 . . . . . . simplify

  x = 20

  y = 56 -20 = 36

The two numbers are 20 and 36.

A. y = 4.5x

Step-by-step explanation:

y is the length of the fish and x is the time, by checking each equation with values in the table you can see that this is the one that represents the relationship.

Example using (4 yrs, 18 cm):

A: 18 = 4.5(4) ✅

B: 4 = 4.5(18) ❌

C: 4 = 9(18) ❌

D: 18 = 9(4) ❌

Answer:

$28

Step-by-step explanation:

given that

The Principal amount is $800

The rate of interest is 3.5%

And, the time period is one year

we need to find out the simple interest

As we know that

Simple interest = Principal × rate × time period

= $800 × 3.5% × 1 year

= $28

hence, the simple interest is $28
