Answer:

1.77 ft.^2

Step-by-step explanation:

What we know: diameter of circle is 1.5

What we need: the radius to find the area of a circle

What we can do: Divide 1.5 by two to get the radius(since the diameter is twice the radius : radius x 2 = diameter)

Math --> 1.5 divide by 2 = .75

What we need to know: Formula of finding Area of Circle is A=(pie)r^2

Insert what we know: A=(pie).75^2

Work out problem(do radius to the second power first)#1: .75^2 = .5625(unrounded)

Work out problem(multiply number by pie))#2: .5625 multiplied by (pie) = 1.7671458676442586966352369030947‬

Round Answer to nearest hundredth: 1.77 ft.

Note: I use the pie sign for this problem. So I used : 3.1415926535897932384626433832795‬

I used a scientific calculator for the calculations.

^2 is added after the unit to show Area.

To the second power is multiplying the number by itself. Example: 4^2 = 16 = 4 x 4

In a particular game, a fair die is tossed. If the number of spots showing is either four or five, you win $1. If the number of

Answer:

The probability that you win at least $1 both times is 0.25 = 25%.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either you win at least $1, or you do not. Games are independent. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Probability of winning at least $1 on a single game:

The die has 6 sides.

If it lands on 4, 5 or 6(either of the three sides), you win at least $1. So

$p = \frac{1}{2} = 0.5$

You are going to play the game twice.

This means that $n = 2$

The probability that you win at least $1 both times is

This is P(X = 2).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{2,2}.(0.5)^{2}.(0.5)^{2} = 0.25$

The probability that you win at least $1 both times is 0.25 = 25%.

Tammy bought a nightstand that was marked down 60% from an original price of $50. If she paid 10% sales tax, what was the total

AURORKA [14]

Answer: the total cost of the nightstand is $22

Step-by-step explanation:

The original price of the night stand is $50. If the original price of the night stand was marked down by 60%, it means that the amount of money by which it was reduced would be

60/100 × 50 = 0.6 × 50 = 30

The new selling price would be

50 - 30 = $20

If she paid 10% sales tax,the amount of tax paid would be

10/100 × 20 = 0.1 × 20 = 2

Therefore, the total cost of the nightstand would be

20 + 2 = $22

What is 7/200 in a decimal

Sliva [168]

Hi there!

To find this you can simply use a calculator. All you have to do is divide the numerator by the denominator to see what you get.

7/200 in decimal form is 0.035. Pretty simple.
This fraction cannot be simplified.

Hope this helps!

Help me fine the intercepts please

borishaifa [10]

Answer: y intercept is (0, 0.4) and the x intercept is (0, 0.3)

Step-by-step explanation: intercept is where the line meets the axis so, we see there that on the y axis it is on 0.4 and on the x axis it is on the middle between 0.2 and 0.4 which makes it 0.3.
