John is playing a game with a standard deck of playing cards. He wants to draw a jack on the first try. Which of the following s

tatements is true?
a. The probability that John draws a jack on the first try is 1/13. If John replaces the card, re- shuffles, and draws again, the probability that he will pull another jack increases.
b. The probability that John draws a jack on the first try is 3/13. If John replaces the card, re- shuffles, and draws again, the probability that he will pull another jack stays the same.
c. The probability that John draws a jack on the first try is 1/13. If John replaces the card, re- shuffles, and draws again, the probability that he will pull another jack decreases.
d. The probability that John draws a jack on the first try is 1/13. If John replaces the card, re- shuffles, and draws again, the probability that he will pull another jack stays the same.

Answer:

d

Step-by-step explanation:

It is a 1/13 chance but even if you shuffle and replace it, its still a 1/13 chance.

Mario has a rectangular prism completely filled with sand that has a base area of 85 cm² and a height of 15 cm. Mario pours all
just olya [345]

The base area of this second rectangular prism is 51 cm²

The rectangular prism completely filled with sand has a base area of 85cm² and height of 15cm .

<h3></h3><h3> volume of a rectangular prism</h3>
  • volume = Bh

where

B = base area

h = height

Since the first rectangular prism was completely filled with sand and it completely filled the second rectangular prism, it means they both have the same volume.

Therefore,

volume of the first rectangular prism = volume of the second rectangular prism.

  • volume  = Bh
  • volume = 85 × 15
  • volume = 1275 cm³

Therefore, the base area of the second rectangular prism can be calculated as follows:

volume = Bh

1275 = 25B

B = 1275 / 25

B = 51 cm²

How to graph y = 2|x + 3| - 4
mr_godi [17]

The x-intercepts and the y-intercepts of the function is that determines the graph is:

  • x-intercepts = (-5,0) and (-1,0)
  • y-intercepts = (0,2)

<h3>How do we graph the function y = f(x) of an absolute equation?</h3>

The function of an absolute equation can be graphed by determining the values of x-intercepts and the y-intercepts of the function.

From the given equation:

y = 2|x+3| - 4

To determine the y-intercepts, we need to set the values of x to zero, and vice versa for x-intercepts.

By doing so, the x-intercepts and the y-intercepts of the function is:

  • x-intercepts = (-5,0) and (-1,0)
  • y-intercepts = (0,2)

Therefore, since we know the x and y-intercepts, the graph of the absolute value can be seen as plotted below.

What is If a rectangular prism has a length, width, and height of centimeter, centimeter, and centimeter, respectively, then the
USPshnik [31]

Answer:

The volume is 105/512 cubic inches

Step-by-step explanation:

Given [Missing from the question]

L = \frac{3}{8} cm -- Length

W=\frac{5}{8}cm -- Width

H = \frac{7}{8}cm -- Height

Required

Determine the volume.

The volume (V) is calculated as thus:

V = L *W *H

V = \frac{3}{8} cm* \frac{5}{8}cm * \frac{7}{8}cm

V = \frac{3}{8} * \frac{5}{8} * \frac{7}{8}cm^3

V = \frac{3*5*7}{8*8*8}cm^3

V = \frac{105}{512}cm^3

Cheyenne drove 3000 miles in 75 hours. At this rate, how long will it take her to drive 4000 miles?
lyudmila [28]
Set up a proportion:
\frac{3000}{75}=\frac{4000}{x}
To solve cross multiply:
3000x=300000
divide both sides by 3000:
3000x/3000=300000/3000
x=100

It will take her 100 hours to drive 4000 miles assuming she continues to travel at this rate.
