Create and Solve an equation to find the unknown angle. ​
valentina_108 [34]

Answer:

Equation: 2x + 3x + 10 = 180

x = 34

Top angle = 68 degrees

Bottom angle = 112 degrees

Step-by-step explanation:

The two angles add to 180, so set them equal to 180.

2x + 3x + 10 = 180

5x + 10 = 180

     - 10    - 10

5x = 170

/ 5    / 5

x = 34

Plug x into angles,

2(34) = 68

3(34) + 10 = 112

Ariel scored on 12 two-point and three-point shots. She scored 27 points in all. How many of each shot did Ariel make? Show work
suter [353]
For this, you multiply the 12 two point shots she made to see how many points she earned
12 x 2 = 24
now you will subtract the 24 from 27 to find out how many points are left
27 - 24 = 3
this means she made 12 two point shots (worth 24 points) and 1 three point shot (worth 3 points) to total up as her 27 points:)

g A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number
nlexa [21]

Complete Question

A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 11 of the plates have blistered. Does this provide compelling evidence for concluding that more than 10% of plates blister under such circumstances?

A) State H_0 and H_a, (5 pts)

B) Test the hypothesis using the P-Value approach at a significance level of 4%: (15 pts)

Expert Answer

Answer:

a)H_0:p=0.10

  H_a:p>0.10

b) We fail to reject Null hypothesis

Step-by-step explanation:

From the question we are told that:

Sample size n=100

No. with blistered x=11

a)

Generally the Hypothesis given as

H_0:p=0.10

H_a:p>0.10

b)

Since p=0.10

Therefore

p'=\frac{11}{100}

p'=0.11

Test statistics

Z=\frac{p'-p}{\sqrt{p(1-p)}}

Z=\frac{0.11-0.10}{\sqrt{0.10*0.90/100}}

Z=1.33

From table

P-Value =0.092

Therefore

P-value >0.04 significance level

Hence,We cannot conclude that at 4\% significance level the proportion is greater than 10\%

We fail to reject Null hypothesis

%50 POINTZ Which set of statements explains how to plot a point at the location (Negative 2.5, 3.75)?
makvit [3.9K]

Answer:

Move 2.5 units left because the x-coordinate is -2.5. -2.5 is between -2 and -3. Move 3.75 units up because they-coordinate is 3.75. 3.75 is between 3 and 4.

Step-by-step explanation:

Look at the picture.

(x ; y)

x < 0 - move x units left

x > 0 - move x units right

y < 0 - move y units down

y > 0 - move y units up

Answer Please first = brainliest only if correct.
Kisachek [45]

Answer:

3x + 2y = 315 -----(1)

2x + 4y = 450 -----(2)

from (1) 3x + 2y = 315

2y = 315-3x

y = 157.5 - 3/2x ---- (3)

substitute (3) into (2)

2x + 4y = 450

2x + 4(157.5 - 3/2x ) = 450

2x + 630 - 6x = 450

-4x = -180

x = 45 ---- (4)

substitute (4) into (3)

y = 157.5 - 3/2x

y = 157.5 - 3/2(45)

y = 90

a haircut,x = 45 minutes

dye hair,y = 90 minutes
