If c = 8 and d = -5:

a) c - 3 = 8 - 3
= 5

b) 15 - c = 15 - 8
= 7

c) 3(c + d) = 3(8 + (-5))
= 3*3
= 9

d) 2c - 4d = 2(8) - 4(-5)
= 16 + 20
= 36

e) d - c^2 = -5 - (8)^2
= -5 - 64
= -69

f) 2d^2 + 5d = 2(-5)^2 + 5(-5)
= 50 - 25
= 25

Need answer ASAP is an assessment!!!!
worty [1.4K]

Answer:

76%, \frac{19}{25}, and Likely

Step-by-step explanation:

The problem tells us that P(red) = 0.76

0.76 as a percentage is represented as 76 out of a 100 or 76%

0.76 as a fraction is \frac{76}{100} which can be simplified to \frac{19}{25} by dividing the numerator and denominator by 4

The probability could be considered "Likely" as it is above 50%

What is the value of x/3y , when x = 18 and y = 3?
tekilochka [14]

So when you work with variables (x, y or any other letter), when they're beside a number it usually means to multiply.

So 3y can also be written as 3(3). So 3 multiplied by 3 is equal to 9

So now our problem looks like this,

x/9.

Since we already know what x is equal to, our problem will look like this

18/9.

So now all we have to do is divide.

18 divided by 9 is 2

So therefore, your answer is 2.


I hope this helps :)

2. Use this box and whisker graph to list the following scores.
Schach [20]

The list of scores from the given box-and-whisker plot are:

Lowest score: 20

Lower quartile (Q1): 30

Median: 60

Upper quartile (Q3): 80

Highest score: 100

The range = 80

<h3>How to Determine the Scores or Data Point from a Box-and-whisker Plot?</h3>

There are specifically 5 values that are referred to as the five-number summary which are displayed by a typical box-and-whisker plot. As shown in the image attached below, these values include the following:

  • The minimum value which is the least value
  • The lower quartile value (Q1)
  • The median value
  • The upper quartile value (Q3),
  • The maximum value which is the largest data score.

Thus, from the box-and-whisker plot that is given in this question, the five-number summary are:

Minimum value (lowest score): 20

Lower quartile value (Q1): 30

Median: 60

Upper quartile value (Q3): 80

Maximum value (highest score): 100

The range = max - min = 100 - 20

The range = 80
