Find the value of x in the figure below if RE is parallel to PM.
2.3 units
16 units
21 units
4.6 units
Answers
Answer:
21 units
Step-by-step explanation:
Since,
RE is parallel to PM,
( AR / RP ) = ( AE / EM )
( 7 / x ) = ( 6 / 18 )
( 7 / x ) = ( 1 / 3 )
x × 1 = 7 × 3
x = 21 units

A sample of size 20 from a normal distribution has sample mean 3.5 and sample variance 14.75. Find 90% confidence intervals for the variance and standard deviation of the distribution.
Answers
Answer:
Variance =9.2983, 27.6927
Standard deviation = 3.0493, 5.2624
Step-by-step explanation:
n = 20
S = 14.75
X² = chisquare
N-1 = degree of freedom
Alpha = 0.1
Alpha/2 = 0.1/2 = 0.05
1-0.1/2 = 0.95
Using statistics table
X² 19,0.05 = 30.14
X² 19, 0.95 = 10.12
A. 19(14.75)/30.14 , 19(14 75)/10.12
= 9.2983, 27.6927 for the variance of the population
B. Standard deviation = square root of variance
= √9.2983, √27.6927
= 3.0493, 5.2624

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.6 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 26 engines and the mean pressure was 4.9 pounds/square inch with a variance of 0.81. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answers
Answer:
Decision Rule; Reject H₀ if t > 1.708
Step-by-step explanation:
Given the data in the question;
sample size n = 26
sample mean x' = 4.9
Variance = 0.81
standard deviation σ = √variance = √0.81 = 0.9
level of significance ∝ = 0.05
Claim;
Null hypothesis H₀ : μ = 4.6
Alternative hypothesis H₁ : μ > 4.6
Test Statistics;
Right tailed test
Now, decision rule for rejecting H₀;
degree of freedom df = n - 1 = 26 - 1 = 25
so, Right tailed test { > in H₁ }
Hence, Critical Value = [tex]t_{\alpha ,df[/tex] = [tex]t_{0.05, 25[/tex] = 1.708
Decision Rule; Reject H₀ if t > 1.708

We want to find the zeros of this polynomial:
p(x) = 2x^3 – x^2 - 8x + 4
Plot all the zeros (z-intercepts) of the polynomial in the interactive graph.
Answers
Answer:
Step-by-step explanation:
The point is that any graphing calculator will work. We use Desmos on Brainly.
The graph below is your complete answer.
You can actually find the zeros by factoring
p(x) = x^2(2x - 1) - 4(2x - 1)
p(x) = (2x - 1) (x^2 - 4)
p(x) = (2x - 1) (x - 2)(x + 2)

Answer:
4.8 km is the answer.
Step-by-step explanation:
a = ?
b = 5 km
c = 7 km
According to the Pythagorean theorem,
a² + b² = c²
a² + 5² = 7²
a² + 25 = 49
a² = 49 - 25
a² = 24
a = 4.8989
Round to the nearest tenth,
a = 4.8 km

10 POINTS FOR THE CORRECT ANSWER PLEASE HELP
Answers
Answer:
Step-by-step explanation:
The Pythagorean theorem says:
[tex]a^2+b^2=c^2[/tex]
where a and b are the two legs of the triangle and c is the hypotenuse. Here, let's say a = 6 and b = [tex]\sqrt{13}[/tex]. We then get the following equation:
[tex]c^2= (6)^2+(\sqrt{13})^2=49[/tex]
So c = 7. Technically, c can also equal -7 since (-7)^2 = 49 as well but that does not apply here because a side length cannot be <0. So 7 is the answer.
