Answer:

The correct option is;

"The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times."

Step-by-step explanation:

Out of the three trials, Jada had the most number of trials (10) and therefore, the highest precision value and the best estimate out of the three   persons that did the trials

The more the sample or trials increase, the more the precision increases as the number of trial comparisons and testing increases.

The increased trials give more information, resulting in a more precise estimate. It also increases the confidence in the result and reduces the amount of uncertainty and increases precision of the results.

Answer:

12 minutes

Step-by-step explanation:

Given the question :

how much time could Robert save on a 60 mile trip if he drove at 70 mph rather than at 50 mph?

Time taken to cover 60 miles at a speed of 50 miles per hour

Recall :

Time taken = distance / speed

Hence, at Speed = 50 mph

Time taken = 60/50

Time taken = 1.2 hours = (1.2 * 60) = 72 minutes

At speed = 70mph

Time taken = 70/50

Time taken = 1.4 hours = (1.4 * 60) = 84 minutes

Time saved :

(84 - 72) = 12 minutes

Answer:  $340

Step-by-step explanation:

Create a proportion with the given values of 800 lbs = $3400

           [tex]\dfrac{dollars}{pounds}:\ \dfrac{3400}{800}=\dfrac{x}{80}[/tex]

Cross Multiply:    800x = 3400(80)

Answer:

893.4 million pounds

Step-by-step explanation:

Total annual consumption of salmon is given by [tex]y=5.59x+837.5[/tex]

Total annual consumption of tuna is given by [tex]y=1.49x+878.5[/tex]

As consumption of salmon is equal to the consumption of tuna,

[tex]5.59x+837.5=1.49x+878.5\\5.59x-1.49x=878.5-837.5\\4.1x=41\\x=\frac{41}{4.1}\\ x=10[/tex]

Put [tex]x=10[/tex] in [tex]y=5.59x+837.5[/tex] to find total annual consumption of salmon.

Therefore,

Total annual consumption of salmon = [tex]5.59(10)+837.5=893.4[/tex] million pounds

Step-by-step explanation:

3(2x - 4) - 2(5x - 2) = -20

6x - 12 - 10x + 4 = -20

-4x - 8 = - 20

-4x = -20 + 8

-4x = -12

x = -12 ÷ -4

x = 3

Answer:

2267 km

Step-by-step explanation:

1890 km/3.5 hours = 2267 km/4.2 hours

2268 km far will the plane fly in 4.2 hours if it maintains the same air speed.

How far will the plane fly in 4.2 hours if it maintains the same air speed?

The formula speed = distance ÷ time can be rearranged like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time. distance = speed × time.

Given,a plane flies 1890 km in 3.5 hours.

So, distance = 1890 km and time = 3.5 hours.

We know,

Distance = Speed × Time

For example, If speed of a car is 20 m/s and the car travel 60 s then the car cover total distance

[tex]= 20 \times 60 = 1200 \: m[/tex]

Again

[tex]speed = \frac{distance}{time}[/tex]

According to question,

Speed

[tex] = \frac{distance}{time} \\ = \frac{1890}{3.5} \\ = 540 [/tex]

So, speed of the plane is 540 km/hour.

Again given time is 4.2 hours

So, Distance = Speed × Time

[tex] = 540 \times 4.2 \\ = 2268 \: km[/tex]

Answer:

Step-by-step explanation:

Company A = 18 eagles for $49.32

Price per eagle = $49.32 / 18

= $2.74

Company B = 16 eagles for $43.36

Price per eagle = $43.36 / 16 eagles

= $2.71

Company C = $41.55 for 15 eagles

Price per eagle = $41.55 / 15 eagles

= $2.77

The company which has the best buy is company C, they sell 1 eagle for $2.77 (highest selling price among the three companies)

Answer:

Width of the rectangular prism

It is given to us that the volume of the rectangular prism is calculated by the given formula :-

v = lwh

Where,

v = volume

l = length

w = width

h = height

Now,

In the question we are given :-

v = 138.24 cubic inches

h =  9.6 inches

l = 3.2 inches

w = ?

Substitute these values in the volume formula given :-

138.24 = 3.2 * w * 9.6

138.24 = 30.72 * w

w = 138.24/30.72

w = 4.5

⇒ The width of the rectangular prism is 4.5 inches.

The required width of the rectangular prism is 4.5 inches.

Given information:

The volume of the rectangular prism is defined as,

[tex]V=lwh[/tex]

where l is the length, w is the width, and h is the height of the prism.

The volume of the prism is 138.24 cubic inches.

The height of the prism is 9.6 inches, and the length of the prism is 3.2 inches.

So, the width of the prism can be calculated as,

[tex]V=lwh\\138.24 =3.2\times w\times 9.6\\138.24 =30.72\times w\\w=\dfrac{138.24}{30.72}\\w=4.5\rm \; inch[/tex]

Therefore, the required width of the rectangular prism is 4.5 inches.
