Given m || n, find the value of x and y.
(3y-17) (6x+20)°
(7x+13)
n
Answer:
Value of x = 7° & y = 45°
Step-by-step explanation:
According to the question m || n.
For x:
[tex] \rm \implies (7x + 13) \degree = (6x + 20) \degree \\ \\ \rm \implies 7x - 6x = 20 \degree - 13\degree \\ \\ \rm \implies x = 7 \degree[/tex]
For y:
[tex] \rm \implies (3y - 17)\degree + (6x + 20) \degree = 180\degree \\ \\ \rm \implies (3y - 17)\degree + (6 \times 7 + 20)\degree = 180\degree \\ \\ \rm \implies (3y - 17)\degree + (42 + 20)\degree = 180\degree \\ \\ \rm \implies 3y - 17\degree + 62\degree = 180\degree \\ \\ \rm \implies 3y + 45\degree = 180\degree \\ \\ \rm \implies 3y = 180\degree - 45\degree \\ \\ \rm \implies 3y = 145\degree\\ \\ \rm \implies y = \bigg( \frac{145}{3} \bigg) ^\degree \\ \\ \rm \implies y = 45\degree[/tex]

You're Welcome :)
If she wants to find the rate at which she burned calories on day 8. C'(8) is: B. 8.75 calories per day
How to find the calories per day?First step is to find the upper and lower values for the burned calories on day 8.
Upper value (C'(8) = 405 - 386 /2
Upper value C'(8) = 19/2
Upper value C'(8) = 9.5
Lower value C'(8) = 386 -370/2
Lower value C'(8) = 16/2
Lower value C'(8) = 8
Now let find C'(8)
C'(8) = 9.5+8/2

a.) find the test statistic
b.) what is the p-value
c.)what is the conclusion about the null hypothesis
d.) what is the final conclusion?
Regarding the hypothesis tested in this problem, it is found that:
a) The test statistic is: t = 0.49.
b) The p-value is: 0.6297..
c) The null hypothesis is not rejected, as the p-value is greater than the significance level.
d) It appears that the students are legitimately good at estimating one minute, as the sample does not give enough evidence to reject the null hypothesis.
What is the test statistic?The test statistic of the t-distribution is given by the equation presented as follows:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which the variables of the equation are given as follows:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the hypotheses.s is the standard deviation of the sample.n is the sample size.The value tested at the hypothesis is:
[tex]\mu = 60[/tex]
From the sample, using a calculator, the other parameters are given as follows:
[tex]\overline{x} = 62.47, s = 19.2, n = 15[/tex]
Hence the test statistic is obtained as follows:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{62.47 - 60}{\frac{19.2}{\sqrt{15}}}[/tex]
t = 0.49.
What are the p-value and the conclusion?The p-value is obtained using a t-distribution calculator, with a two-tailed test, as we are testing if the mean is different a value, in this case 60, with:
15 - 1 = 14 df, as the number of degrees of freedom is one less than the sample size.t = 0.49, as obtained above.Hence the p-value is of 0.6297.
Since the p-value is greater than the significance level of 0.01, the null hypothesis is not rejected, attesting to the ability of the students to estimate one minute.

Suppose that the Mathematics marks of all the students in the class are normally distributed with mean mark 54 and standard deviation 16. What is the probability that a student's mark is more than 75? In a class of 50 students, how many students should have a mark of more than 75?
The probability that a student's mark is more than 75 is 0.0947 and in a class of 50 students, 5 students should have a mark of more than 75.
In the given question,
The Mathematics marks of all the students in the class are normally distributed with mean mark 54 and standard deviation 16.
We have to find the probability that a student's mark is more than 75.
In a class of 50 students, we also have to find how many students should have a mark of more than 75.
From the question the mean = 54
Standard Deviation = 16
So the probability that a student's mark is more than 75.
Using the normal distribution
z = (x−mean)/Standard Deviation
P(x>75) = P(z>(x−mean)/Standard Deviation)
P(x>75) = 1−P(z<(75−54)/16)
Simplifying
P(x>75) = 1−P(z<21/16)
P(x>75) = 1−P(z<1.3125)
From the standard z table value
P(x>75) = 1−0.9053
P(x>75) = 0.0947
Hence, the probability that a student's mark is more than 75 is 0.0947.
Now finding in a class of 50 students, how many students should have a mark of more than 75.
Total student = 50
So the student having mark of more than 75 = Total student * probability that a student's mark is more than 75
The student having mark of more than 75 = 50 * 0.0947
The student having mark of more than 75 = 4.735
The student having mark of more than 75 ≈ 5
Hence, in a class of 50 students, 5 students should have a mark of more than 75.

Compound interest is calculated as follows:Initial balance = 1 + (interest rate / period's worth of compoundings).acc to our question-
Step-by-step explanation:
1.5% = 0.015 , 4% = 0.04 , 5% = 0.05
16,000 × 0.015 = $240.00
$25,000 × 0.04 = $1,000.00
$2,250.00 - ($240.00 + $1,000.00) = $1,010.00
$1,010.00 ÷ 0.05 = $20,200.00
$20,200.00 + $25,000.00 + $16,000.00 = $61,200.00
hence,She made sales of =$61,200.00

A child welfare officer asserts that the mean sleep of young babies is 14 hours a day. A random
sample of 64 babies shows that the mean sleep was only 13 hours 30 minutes with standard
deviation of 3 hours. At 5% level of significance, test the assertion that the mean sleep of babies is
less than 14 hours a day
There is not enough evidence to conclude that the mean is less than 14 hours, as the p-value of the test is greater than 0.05, using the t-distribution.
What are the hypothesis tested?At the null hypothesis, it is tested if the mean is not less than 14 hours, hence:
[tex]H_0: \mu \geq 14[/tex]
At the alternative hypothesis, it is tested if there is enough evidence that the mean is less than 14 hours, hence:
[tex]H_1: \mu < 14[/tex]
What is the test statistic?The test statistic is given by the equation presented as follows:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which the parameters are defined as follows:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.In the context of this problem, the values of these parameters are:
[tex]\overline{x} = 13.5, \mu = 14, s = 3, n = 64[/tex]
Hence the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{13.5 - 14}{\frac{3}{\sqrt{64}}}[/tex]
t = -1.33.
P-value and conclusionUsing a z-distribution calculator, with a left-tailed test, as we are testing if the mean is less than a value, with t = -1.33 and 64 - 1 = 63 df, the p-value of the test is of 0.094.
Since the p-value of the test is greater than the significance level of 0.05, there is not enough evidence to conclude that the mean is less than 14 hours.
