Austin drove 140 miles in two hours what was his average speed

Answer:

There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

Step-by-step explanation:

H0 : μ = 3.8

H1 : μ < 3.8

Test statistic :

(x - μ) ÷ s/sqrt(n)

(3.7 - 3.8) ÷ 0.6/sqrt(60)

Test statistic = - 1.29

The Pvalue from test statistic :

P(z < -1.29) = 0.0985

Reject Null if

Pvalue < α

0.0986 > 0.01 ; Hence, we fail to reject the null ;

There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

65/10=6.5

Answer:

The number is 1.6 .

x = 1.6

Answer:

Theta = 59 degrees

Step-by-step explanation:

Here, we want to get the value of the marked angle

To do this, we use the appropriate trigonometric ratio

From what we have,

The side 42 ft is adjacent the angle given

The side facing the right angle is 82 ft

The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse

Cos theta = 42/82

theta = cos^-1 0.5122

theta= 59.189

To the nearest degrees, this is 59 degrees

Answer:

8x+5

Step-by-step explanation:

it would be 8x+5.

this is because 8x and 5 are not like terms so they cannot be collected which means that the answer is 8x+5

Answer:

x = 6

y = 45 degrees

Step-by-step explanation:

Here, we want to get the measure of x and y

For a 45-45-90 triangle, the measure of each of the internal angle asides the right angle is 45 degrees

This mean y is 45

To get x, we know we have an isosceles triangle

So the length of the third ungiven leg is x too

Mathematically, the square of the hypotenuse (side facing the right angle) is equal the sum of the squares of the two other sides

(6 √2)^2 = x^2 + x^2

72 = 2x^2

x^2 = 72/2

x^2 = 36

x = √36

x = 6

Answer:

3 < y ≥ -3

Step-by-step explanation:

R = 3 < y ≥ -3

The line can't go beyond 3 and also cant be less than -3.

Answer:

11.2 Slices / Week

Step-by-step explanation:

We know that Jake has eaten 5 slices of cake in 3 days. You can divide 5 / 3 to get an average of 1.6 slices of cake being eaten per day. The question asks what the weekly rate or eating the cake will be, do you need to multiple 1.6 x 7 for the total amount of cake eaten per week, which is 11.2 slices!

Answer:

square = 8

triangle = 3

circle = 2

Step-by-step explanation:

triangle + triangle = 6, one triangle = 3

triangle + circle = 5, circle = 5 - 3 = 2

square + circle = 10, square = 8

Answer:

120°

Step-by-step explanation:

31 + 29 = 60

180 - 60 = 120

Answer:

A = 9r^2

Step-by-step explanation:

r=√A/3

multiply both sides by 3

3r = √A

Square both sides

3^2 * r^2 = A

9r^2 = A

Answer A: Reflection over x axis

Answer:

C. Reflection over x-axis

Step-by-step explanation:

Each time you reflect something over the x-axis, the x-coordinate stays the same, but the y-coordinate changes.

Answer:

1. $27.30 2. $48.00 3. $15.75 4. $24.20 5. $31.00 6. $40.80

Step-by-step explanation:

1. $13.00 + (1.10)($13.00)

= $ 27.30

2. $60.00 - $60.00(0.20)

= $48.00

3. $15.00 + $15.00(0.05)

= $15.75

4. $22.00 + $22.00(0.10)

= $24.20

5. $25.00(0.06) + $25.00(0.18) + $25.00

= $31.00

6. $32.00(0.075) + $32.00(0.20) + $32.00

= $40.80

For this case we have the following functions:

y = 4x

y = 4 ^ x

We observed that :

The graph y = 4 ^ x is growing faster than y = 4x, because for smaller values of x, it has the same range as y = 4x.

Answer:

The graph y = 4 ^ x is growing faster than y = 4x

Answer:

8

Step-by-step explanation:

If each baseball= 4 homeruns, and Chester has 5 baseballs next to his name (20 homeruns), then Evan hit 12 home runs because 4*3= 12 and he has 3 baseballs next to his name.

Answer:

Equation: 5x = 90

x = 18

<LNM = 54degrees

Step-by-step explanation:

From the diagram shown;

<JNK + <KNL + <LNM = 90

x + x + 3x = 90

5x = 90

x = 90/5

x = 18

The equation 5x = 90 can be used to solve for x

Get <LNM = 3x

<LNM = 3(18)

<LNM = 54 degrees

Answer:

two

Step-by-step explanation:

its really easy if u think abt it

Answer:

infinitely many

Step-by-step explanation:

y=0 is right on the x-axis, so therefore there would be infinitely many             x-intercepts because they are on the x-axis.

Answer:

I believe the answer is '22.82' which would then become '22.8' when rounded to the nearest tenth.
