L = 5[tex]\sqrt{10}[/tex]

Step-by-step explanation:

use Pythagorean Theorem:

L² + (5[tex]\sqrt{2}[/tex])² = (10[tex]\sqrt{3}[/tex])²

L² + 25(2) = 100(3)

L² + 50 = 300

L² = 250

L = [tex]\sqrt{250}[/tex] = [tex]\sqrt{25}[/tex] · [tex]\sqrt{10}[/tex] = 5[tex]\sqrt{10}[/tex]

Answer:

by Pythagoras law

(10√3)²=l²+(5√2)²

100×3-25×2=l²

l²=25o

l=√250=5√10

:.l=5√10

Which of the following are exterior angles? Check all that apply

Answers

Answer: D, C, A

Step-by-step explanation:

An exterior angle is an angle that is supplementary to an interior angle.

The angle between the extended side and its adjacent side is called the exterior angle so the option (D), (C), and (A) will be the correct answers.

What is the Exterior angle?

Exterior angles become by a side of that figure and its extended adjacent side.

The exterior angle has been attached.

Since in the graph angle, ∠3 become by two extended lines but for exterior angle, there should be only one extended line which is ∠6, ∠5, and ∠2.

Hence angles ∠6, ∠5, and ∠2 will be the exterior angles.

What is the rate of return when 30 shares of Stock
A, purchased for $15/share, are sold for $480? The
commission on the sale is $6.
Rate of Return = [?] %
Give your answer as a percent rounded to the
nearest tenth

Answers

Answer:

5.1%

Step-by-step explanation:

We are told that 30 shares of Stock are purchased for $15/share..

This gives a total value of: 30 × 15 = $450.

Now,they are sold for $480 with a commission of $6. This means the final money getting to the seller is; 480 - 6 = $474.

Thus; rate of return percentage = (474 - 450)/474) × 100% = 5.06%

To the nearest tenth gives; 5.1%

The rate of return is 5.1%.

Given that,

A, purchased for $15/share, are sold for $480.The  commission on the sale is $6.

Based on the above information, the calculation is as follows:

The total value should be

[tex]= 30 \times 15[/tex]

= $450.

Since it is sold for $480 along with commission of $6 so final money should be  

= 480 - 6

= $474.

Now rate of return is

[tex]= ((474 - 450)\div 474) \times 100%[/tex]

= 5.06%

= 5.1%

A line has a slope of 7. One of the points on the line is (3,5). Which of the following could be
another point on the line?
A. (-1, -24)
B. (-2, -30)
C. (6, 24)
D. (10,55)

Answers

Answer:

c

Step-by-step explanation:

I think

The points that could be on the line

y = 7x - 16 are (-2, -30)

-30 = 7 X -2 - 16

-30 = -14 - 16

-30 = -30

Option B is the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line has a slope = 7 and passes through the point (3, 5).

Now,

The equation of a line can be written as,

y = mx + c

m = 7

y = 3x + c

Now,

(3, 5) = (x, y)

5 = 7 x 3 + c

5 = 21 + x

5 - 21 = c

c = -16

The equation of the line.

y = 7x - 16

The points that could be on the line have to satisfy the equation.

y = 7x - 16

A.

(-1, -24)

y = 7 x -1 - 16 = -7 - 16 = -23

This is not true

B.

(-2, -30)

y = 7 x -2 - 16 = -14 - 16 = -30

This is true.

C.

(6, 24)

y = 7 x 6 - 16 = 42 - 16 = 26

This is not true.

D.

(10,55)

y = 7 x 10 - 16 = 70 - 16 = 54

This is not true.

Thus,

The points that could be on the line

y = 7x - 16 are (-2, -30)

-30 = 7 X -2 - 16

-30 = -14 - 16

-30 = -30

Option B is the correct answer.

Find the x and y intercepts for the following equation. 4x - 2y = 16

Answers

Answer:

( 4, 0 ) and ( 0,-8 )

Step-by-step explanation:

→ Rearrange into y = mx + c format

4x - 2y = 16

→ Minus 4x from both sides

-2y = -4x + 16

→ Divide everything by 2

-y = -2x + 8

→ Multiply everything by -1

y = 2x - 8

→ Substitute x = 0 to find the y-intercept and y = 0 to find the x intercept

x = 0 then y = -8 so ( 0,-8 )

y = 0 then x = 4 so ( 4, 0 )

NeverReady batteries has engineered a newer, longer lasting AAA battery. The company claims this battery has an average life span of 17 hours with a standard deviation of 0.7 hours. Your statistics class questions this claim. As a class, you randomly select 30 batteries and find that the sample mean life span is 16.7 hours. If the process is working properly, what is the probability of getting a random sample of 30 batteries in which the sample mean lifetime is 16.7 hours or less

Answers

Answer:

0.020

Step-by-step explanation:

Given that,

μ = 17,

σ = 0.7,

x¯ = 16.7 hours

n(number of batteries) = 30

To find,

The probability(e) by using μ\frac{σ}{[tex]\sqrt{n}[/tex]} = normal cdf

∵ (E - 99, 16.7 , 17, 0.8/[tex]\sqrt{30}[/tex])

The probability of getting a random sample of 30 batteries = 0.020

Hence, the claim is reasonable as only 2% of batteries are likely to last till 16.7 hours.
