On the spinner below, what is P(red or blue)? point)4. On the spinner below, what is P(not purple)? point

Answers

Answer 1

Answer:

Answer:

$\text{P(red or blue)}=(3)/(4)\n\n\text{P(not purple)}=1$

Step-by-step explanation:

3. From the given spinner, the number of red sections = 3

Number of blue sections= 3

Then, the number of sections which are red or bl;ue = 3+3=6

Total sections=8

Then ,

$\text{P(red or blue)}=\frac{\text{Number of sections which are red or blue}}{\text{Total}}\n\n\Rightarrow\text{P(red or blue)}=(6)/(8)=(3)/(4)$

4. From the given spinner, the number of purple sections =0

Total sections= 8

Number of sections which are not purple =8

Now, $\text{P(not purple)}=\frac{\text{Number of sections which are not purple}}{\text{Total sections}}\n\n\Rightarrow\text{P(not purple)}=(8)/(8)=1$

The Parks Department wants to put a sidewalk diagonally across a square park. The perimeter of the park is 8 miles. a. What is the width of the park?

What will the length of the sidewalk be? Round your answer to the nearest tenth

Answers

The width of the part is 2 miles, this is because the park is square which means all sides are equal. This is computed by dividing 8 miles by 4 sides of the park which give us the answer of 2 miles. The length of the side walk is 2.8 miles. This computed using Pythagorean Theorem, which states that the hypotenuse is solve by the square root of the square of both sides. Then will give us the answer of 2.8 miles.

Write and solve a problem involving money that can be solved with a division equation and has a solution of 1,350 plz answer I need help in honestly hopeless

Answers

Answer:

The problem,

Two friends decided to split the money spent on the lunch. If the lunch costs $2,700, how much money does each have to contribute?

involves division $(2700)/(2)$ to give the solution $1,350.

Step-by-step explanation:

We are required to write a problem which involves division equation and the solution should be 1,350.

Let us consider the problem.

Two friends decided to split the money spent on the lunch. If the lunch costs $2,700, how much money does each have to contribute?

So, the solution is given by,

Total amount of the lunch = $2,700

Since the money is divided among both the friends.

So, the money each person have to contribute = $(2700)/(2)$ = $1,350.

Thus, each person have to contribute $1,350.

A light rail service claims to be on time 98% of the time.Jeanette takes the light rail 40 times in one month how many times can she predict she will be on time is the light rails claim accurate if she is late 6 times

Answers

Answer:

Jeanette would be on time on 85% of her trips.

Step-by-step explanation:

If the light rail service claims to be on time 98% of the time, it should arrive on time at least 39 of 40 times, as 40 x 98 / 100 is equal to 39.2. In consequence, as Jeanette's service arrived late in 6 of over 40 times, we can affirm that what the light rail stated was incorrect. A delayed service in 6 of 40 times has a punctuality rate of 85%, since 6 is the 15% of 40 (40 x 15 / 100 = 40).

If the claim is accurate she should be on time

98% x 40 =
.98 x 40 = 39.2 times out of 40

If she is late 6 times, the claim is inaccurate.
