100 pages a hour

This is a fraction equal to
300 Pages ÷ 3 hours

We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 3

300 Pages ÷ 3
3 hours ÷ 3
=
100 Pages
1 hour
=
100 Pages
hour
= 100 Pages per hour

Answer:

A). Options (C) and (E)

B). 4.8 times

Step-by-step explanation:

Part A

Volume of cylinder (1) = πr²h

= π(6)²(5)

= 565.5 cubic inches

Volume of cone (1) = $\frac{1}{3}\pi (r)^2h$

= $\frac{1}{3}(\pi )(6)^2(5)$

= 188.5 cubic inches

Volume of cylinder (2) = πr²h

= π(6)²(15)

= 1696.5 cubic inches

Volume of cone (2) = $\frac{1}{3}\pi (r)^2h$

= $\frac{1}{3}\pi (6)^2(15)$

= 565.5 cubic inches

Volume of sphere = $\frac{4}{3}\pi r^{3}$

= $\frac{4}{3}\pi (6)^{3}$

= 904.8 cubic inches

Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.

Options (C) and (E) are the correct options.

Part (B)

$\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}$ = $\frac{904.8}{188.5}=4.8$

Therefore, volume of sphere is 4.8 times the volume of cone (1).

Brianna is going to the amusement park, where she has to pay a set price of

Ronch [10]

Im pretty sure the answer is A but if not then it is C

This is bcuz B doesn’t make sense because the graph doesn’t say anything close to 100 rides and D doesn’t make sense either.

Hope this helped.

It is known that 70% of the customers in a sporting goods store purchase a pair of running shoes. A random sample of 25 customer

gogolik [260]

Answer:

=BINOMDIST(10,25,70%,FALSE) -BINOMDIST(5,25,70%,FALSE)

0.001324586

Step-by-step explanation:

The success probability is p = 70% = 0.70

The number of trials are n = 25

The Excel formula for the binomial distribution is given by

BINOMDIST(Number_s, Trial_s, Probability_s, Cumulative)

Where

Numbers = 5 and 10

Trials = 25

Probability = 70%

Cumulative = FALSE

The probability of between 5 and 10 customers is then

=BINOMDIST(10,25,70%,FALSE) -BINOMDIST(5,25,70%,FALSE)

0.001324586

Note: FALSE option provides the probability of exactly 10 and 5 where TRUE option gives cumulative results (0 to 5 or 0 to 10) that would be wrong in this case.

Easy question:

Delvig [45]

Answer:

3 hours and 45 minutes

Step-by-step explanation:

let's assume the tank has a volume of x liters.

let's assume the speed of filling it is x/6 liters per hour for A and x/10 liters per hour for B.

the formula to calculate the time is:

time = volume / speed

If the pumps work together, the total speed is x/6 + x/10, which is 16/60 x

So the time this takes is:

time = x / (16/60 x) = 60/16 hours = 3.75 hours = 3 hours and 45 minutes.
