A number is multiplied by 20, and that product is added to 5. The sum is equal to the product of 5 and 13.

liubo4ka [24]

Answer:

x = 3

Step-by-step explanation:

First, you will pick the first equation :

(x*20)

Then the next,

(x*20) + 5

Then the last equation,

(x*20) + 5 = 5*13

Then you solve

20x + 5 = 65

20x = 65 - 5

20x = 60

20x/20 = 60/20

x = 3

Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe an

elena-s [515]

Answer and Explanation:

Number of classes = 8

Highest value =2300

Lowest value = 1250

Class width= highest value – lowest value / number of classes

= 2300 – 1250/8

= 131.25 = 132

So, we can write class as 1250+132=1382

Class frequency

1250-1382 2

1382-1514 3

1514-1646 6

1646-1778 2

1778-1910 3

1910-2042 2

2042-2174 1

2174-2306 1

All Seasons Plumbing has two service trucks that frequently need repair. If the probability the first truck is available is 0.75

oksano4ka [1.4K]

Answer: There is a probability of 0.05 that there is neither truck is available.

Step-by-step explanation:

Since we have given that

Probability that the first truck is available = 0.75

Probability that the second truck is available = 0.50

Probability that both trucks are available = 0.30

So, probability that either first truck or second truck is available is given by

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.75+0.50-0.30\\\\P(A\cup B)=0.95$

We need to find the probability that neither truck is available.

so, P(A∪B)'=1-P(A∪B)

$P(A\cup B)'=1-0.95=0.05$

Hence, there is a probability of 0.05 that there is neither truck is available.
