Answer:

B = (3, 3)

Step-by-step explanation:

Since the line segment is fifteen units long, from the looks of it, chopping ⅓ of A's side, led to the ordered pair of (3, 3).

The sum of two angle measures 130 degrees. The difference in the two angle measures is 12 degrees. What are the two angle measur

san4es73 [151]

Answer:

59°, 71°

Step-by-step explanation:

This is a "sum and difference" problem. All problems of this type have the same answer: the larger of the two numbers is the average of those given.

Then the larger angle is (130 +12)°/2 = 71°. The smaller is 71° -12° = 59°.

More detailed solution

There are several ways to get there using equations. You can, for example, let L represent the larger number. Then L - D will be the smaller one (where D represent the difference). The sum of the two numbers (S) is ...

L + (L -D) = S

2L = S + D . . . . collect terms, add D

L = (S+D)/2 . . . the larger number is the average of the sum and difference

The sets E and A are given below.

xxTIMURxx [149]

Intersection of E and A: E n A = { 8 }

Union of E and A : E U A = { -2, 3, 0, 6 , 8 }

Solution:

The sets E and A are given below:

E = { -2, 3, 8 }

A = { 0, 6 , 8 }

Find the intersection of E and A

Intersection of E and A means that, set containing all elements of E that also belong to A

Therefore,

From sets E and A,

E n A = { 8 }

Find the union of E and A

union of E and A contains all elements of set E and set A

E U A = { -2, 3, 0, 6 , 8 }

n engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that

BartSMP [9]

Answer:

The calculated t- value = 1.11 > 2.89 at 0.025 level of significance

Null hypothesis is rejected

The engineer designed the valve such that it would produce a mean pressure is not equal to 5.4

Step-by-step explanation:

Step(i):-

Given mean of the Population (μ) = 5.4

Given sample size 'n' = 9

Mean of the sample (x⁻) = 5.7

Standard deviation of the sample (s) = 0.81

Step(ii):-

Null Hypothesis: H₀: The engineer designed the valve such that it would produce a mean pressure of 5.4

H₀: μ = 5.4

Alternative Hypothesis : H₁: μ ≠ 5.4

Level of significance = 0.025

Test statistic

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{5.7 -5.4}{\frac{0.81}{\sqrt{9} } }$

t = 1.11

Degrees of freedom

ν = n-1 = 9-1 =8

t₀.₀₁₅ , ₈ = 2.89

The calculated t- value = 1.11 > 2.89 at 0.025 level of significance

Null hypothesis is rejected

The engineer designed the valve such that it would produce a mean pressure is not equal to 5.4
