Answer:

A)4.6 yard

Step-by-step explanation:

[tex]x^{2} +10^{2} =11^{2} \\x^{2} =21\\x=\sqrt[2]{21} \\[/tex]

x≅4.6

Hoped I helped, have a nice day!

Answer:

y = 4x - 2

Step-by-step explanation:

→ First find the gradient

[tex]\frac{x2-x1}{y2-y1} =\frac{30-2}{8-1} = 4[/tex]

→ Put into y = mx + c format

y = 4x + c

→ Substitute ( 1 , 2 ) into y = 4x + c

2 = 4 + c so c = -2

→ Rewrite into equation format

y = 4x - 2

Answer:

she ran 5,280 yards

Step-by-step explanation:

Answer:

5280

Step-by-step explanation:

Well, there are 1760 yards in a mile, aka 5280 feet. (5280ft/3=1760yds). 1760x3=5280.  I hope this was an okay explanation, this is my first day on Brainly with an account, hehe.

Answer:

B. 12

Step-by-step explanation:

First, we need the degrees for A. So, cosx = 5/13    =    67.4

Now it will be easy to solve a. tan67.4° = a/5    =   12.011728511....

we round it to the nearest tenth and we get 12.

Answer:

x = 121

Step-by-step explanation:

all angles sum = 540

87 + 92 + 105 + 135 = 419

540 - 419 = 121

the answer to your question is 104 degrees.

Answer:

Answer:(A.)

Step-by-step explanation:The reason why its a its because that 13x8=104x17=1,768/3=589.3. Therefore 589.3 can not be round to the nearest tenth.

Answer:

1. 112.364<μ,131.636

2. mean = 122

3. critical value = +-2.1318

Step-by-step explanation:

117+118+140+116+119/5

= 610/5

= 122

the sample mean = 122

the sample standard deviation

s² = (117-122)²+(118-122)²+(140-122)²+(116-122²)+(119-122)²/5-1

= 25+16+324+36+9/4

= 410/4

= 102.5

s² = 102.5

s = √102.5

s= 10.12

SE = s/√n

= 10.12/√5

= 4.52

degree of freedom = 5-1 = 4

critical value of t = +-2.1318 using soft ware

confidence interval =

mean +- t(SE)

122-(2.1318)(4.52), 122+(2.1318)(4.52)

= [112.364, 131.636]

112.364<μ,131.636

therefore these are the answers in the ordre it was given in the question

1. 112.364<μ,131.636

2. mean = 122

3. critical value = +-2.1318

Answer:

First time=7hours

First speed=990km/hour

First distance=first time×first speedD=(

S×T)

D=990km/hr×7hrs

D=6930km.

Second time=6&14min.

Second speed=920km/hr

Second distance=second speed×second time (D=s×t)

D=920km/hr×6&14min.

D=1500

Total distance=6930+1500

=8430

Answer:

First, it’s already telling you that you need to find d, which is the opposite of degree 59. This means you have to do the exact thing for degree 37. Since it’s already telling you to use sine, you need to look at the opposite side of 37 which is 98.4.

So ? is 98.4

Now, you need to find sin 59 / d.

First, plug in sin 98.4 sin (37) in your calculator (make sure it’s in degree setting)

The result is 59.2.

Now, 59.2 = sin 59 / d.

Switch sides like this: d = 59.2 sin (37)

And the answer is approximatley d = 35.6

? = 98.4

d = 35.6

Answer:

1200

Step-by-step explanation:

Answer:

18.The answer is 47 . 5 %

19.The answer is 83 . 85 %

Step-by-step explanation:

18 . This is a good example of normal Distribution

Z = ( Given score - Mean ) / Standard deviation

Z = (16. 36 - 15 .4 ) / 0.48

Z= 0. 96 / 0.48

Z = 2

From the table, the value of z on the right side of the normal curve

= 0.34 + 0 . 135 = 0.475

The percentage is 0. 475 x 100 = 47 . 5 %

19. We are asked to get the percentage between 13. 96 and 15. 88

Z 1 = ( 13 .96 - 15. 4 ) / 0.48

Z 1 = - 1. 44 / 0.48

Z 1 = -3

Z 2 = ( 15 . 88 - 15 . 4 ) / 0. 48

= 0. 48 / 0.48

Z 2 = 1

From the table , the value of z from - 3 to 1 is 0. 34 + 0. 135 + 0. 0235 + 0.34

= 0 .8385

The percentage is 0 . 8385 x 100 = 83 . 85 %
