One hundred sixty people were surveyed and asked if they believed in UFOs, ghosts, and Bigfoot.

HACTEHA [7]

Answer:

Number of people surveyed believed in at least one of these things = 83

Step-by-step explanation:

Given,

Total number of people, n(T) = 160

number of people believe in UFOs, n(U) = 42

number of people believe in ghost, n(G) = 45

number of people believe in Bigfoot, n(B) =21

number of people believe in UFOs and ghost, n(U ∩ G) = 11

number of people believe in Bigfoot and ghost, n(B ∩ G) = 6

number of people believe in UFOs and Bigfoot, n(U ∩ B) = 4

number of people who believe in all, n(U ∩ G ∩ B) = 2

We have asked to draw the Venn diagram and to calculate the number people surveyed believed in at least one of these things .

So, according to Venn diagram,

Number of people surveyed believed in at least one of these things = 25+11+4+2+26+9+6 = 83

Number of people surveyed believed in at least one of these things = 83

Please help me with this question. I will mark you brainliest.

solong [7]

Answer:

Option D : $153

This is how I got that:

9:30 AM to 1:15 PM = 3 hours and 45 minutes

The first hour charges $15 and for the remaining 2 hours and 45 minutes

Mr. Anand is charged 36$. Remember it says that each additional hour or part thereof, so the 2 hours and 45 minutes is considered 3 hours.

So our total for one paddle boat is $51

But Mr. Anand hired three boats so we simply times 51 by 3 and get our solution to the problem:

Mr. Anand must pay $153 or Option D

Give the solution set for the inequality 7x < 7(x - 2) in interval notation.

eduard

ANSWER:

The solution set for the inequality 7x < 7(x - 2) is null set $\varnothing$

SOLUTION:

Given, inequality expression is 7x < 7 × (x – 2)

We have to give the solution set for above inequality expression in the interval notation form.

Now, let us solve the inequality expression for x.

Then, 7x < 7 × (x – 2)

7x < 7 × x – 2 × 7

7x < 7x – 14

7x – (7x – 14) < 0

7x – 7x + 14 < 0

0 + 14 < 0

14 < 0

Which is false, so there exists no solution for x which can satisfy the given equation.

So, the interval solution for given inequality will be null set

Hence, the solution set is $\varnothing$

The height and weight of adults can be related by the equation y=48.3x−127 where x is height in feet and y is weight in pounds.

suter [353]

we conclude that the correct option is A, the slope is:

"the average number of pounds per foot tall"

<h3>What does the slope of the line represent?</h3>

The linear equation:

y = 48.3*x - 127

Relates the height, x, and the weight, y of an adult.

Then the slope, which is 48.3, should have units of mass over height.

Now, if x is in feet and y is in pounds, then the slope has units of pounds/feet.

Then it represents the mean number of pounds per feet. So we conclude that the correct option is A:

"the average number of pounds per foot tall"
