Answer:
Step-by-step explanation:
You have to assume that the triangles are congruent or at least similar. If they are not, the question isn't possible.
If that is so, then <M and <X are equal.
You can find < M by stating that 20 degrees.
That's because <L + <M + <N = 180 degrees. All triangles have 180 degrees.
<L = 70 Given
<N= 90 So marked.
70 + <M + 90 = 180
<M = 20 degrees.
<X = <M
<X = 20

A washer and a dryer cost $1024 combined. The washer cost $74 more than the dryer. What is the cost of the dryer
Answers
Answer:
Let the dryer cost x.
Then, the washer costs (x+87)
Together, they cost (x) + (x+87) = 787
2x+87 = 787
2x = 700 [subtract 97 from both sides]
x = 350 [divide both sides by 2]
The dryer cost $350.
Check: The washer cost $437. Together, they cost $787 [good to check, right?]

Step-by-step explanation:
4cd - 25c^2 - 0.16d^2
= 4cd - (5c)^2 - (0.4d)^2
= -[(5c)^2 -2*5*0.4cd + (0.4d)^2]

An Isosceles Triunde

3x^4 - 6x-1 unit.
The Perimeter of the
triangle is
7x^4 - 3x^3-x-6
Find the Base.
Answers
Answer:
base = [tex]x^4 - 3x^3+11x-4[/tex]
Step-by-step explanation:
An isosceles triangle has 2 sides of equal length (a) and base (b)
⇒ perimeter of an isosceles = 2a + b
Given:
[tex]\textsf{leg (a)}=3x^4 - 6x-1[/tex] [tex]\textsf{perimeter}=7x^4 - 3x^3-x-6[/tex][tex]\implies \textsf{perimeter}=2a+b[/tex]
[tex]\implies 7x^4 - 3x^3-x-6=2(3x^4 - 6x-1)+b[/tex]
[tex]\implies 7x^4 - 3x^3-x-6=6x^4 - 12x-2+b[/tex]
[tex]\implies x^4 - 3x^3+11x-4=b[/tex]
Therefore, base = [tex]x^4 - 3x^3+11x-4[/tex]
Answer:
Perimeter=sum of sides
Let base be y[tex]\\ \tt\longmapsto 3x^4-6x-1+3x^4-6x-1+y=7x^4-3x^3-x-6[/tex]
[tex]\\ \tt\longmapsto 6x^4-12x-2+y=7x^4-3x^3-x-6[/tex]
[tex]\\ \tt\longmapsto y=x^4-3x^3+11x-4[/tex]

A university is comparing the grade point averages of theater majors with the grade point averages of history majors. The university currently has 50 total theater majors and 50 total history majors. The mean and standard deviation for each population are shown in the table.
Theater Majors - (Population Mean 3.22 , Population Standard Deviation 0.002)
History Majors - (Population Mean 3.24 , Population Standard Deviation 0.08)
The university wants to test whether there is a significant difference in GPAs for students in the two majors. What is the P-value and conclusion at a significance level of 0.05?
Answers
Using the z-distribution, as we have the standard deviation for the population, we have that the correct option is:
The p-value is of 0.0772. Fail to reject the null hypothesis that there is no difference in the GPA's.
What are the hypothesis tested?At the null hypothesis, we test if there is no difference in the means, that is:
[tex]H_0: \mu_T - \mu_H = 0[/tex]
At the alternative hypothesis, we test if there is a difference, that is:
[tex]H_1: \mu_T - \mu_H \neq 0[/tex]
What is the distribution of the sampling distribution of sample differences?For each sample, we have that:
[tex]\mu_T = 3.22, s_T = \frac{0.002}{\sqrt{50}} = 0.00028284271[/tex]
[tex]\mu_H = 3.24, s_H = \frac{0.08}{\sqrt{50}} = 0.01131370849[/tex]
Hence:
[tex]\overline{x} = \mu_T - \mu_H = 3.22 - 3.24 = -0.02[/tex]
[tex]s = \sqrt{s_T^2 + s_H^2} = \sqrt{0.00028284271^2 + 0.01131370849^2} = 0.0113[/tex]
What is the test statistic?It is given by:
[tex]z = \frac{\overline{x} - \mu}{s}[/tex]
In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis, hence:
[tex]z = \frac{\overline{x} - \mu}{s}[/tex]
[tex]z = \frac{0.02 - 0}{0.0113}[/tex]
[tex]z = -1.77[/tex]
What is the p-value and the decision?Using a z-distribution calculator, considering a two-tailed test, as we are testing if the mean is different of a value, with z = -1.77, it is found that the p-value is of 0.0772.
Since the p-value is greater than the significance level of 0.05, the correct option is:
The p-value is of 0.0772. Fail to reject the null hypothesis that there is no difference in the GPA's.
