State the slope and y-intercept of the graph of y = x – 7.

Eduardwww [97]

By slope you mean gradient? If yes then it’s 1 and the y intercept is (0, -7)

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 17 Pennies 10 Dimes 19 Nickels

MatroZZZ [7]

Answer:

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of grabbing a nickel:

19 nickels out of 17+10+19+23 = 69 coins, so:

$P(A) = \frac{19}{69}$

Probability of grabbing a penny, considering the first coin grabbed was a nickel:

17 pennies out of 68 coins. So

$P(B|A) = \frac{17}{68} = \frac{1}{4}$

What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny?

$P(A \cap B) = P(A)P(B|A) = \frac{19}{69} \times \frac{1}{4} = \frac{19}{69*4} = 0.0688$

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.

A circular plate has circumference 32 inches. What is the area of this plate? Use 3.14 for pi. The area of this plate is about

Levart [38]

Answer: The area of the plate is 81.67 in^2

Step-by-step explanation:

If we have a circle of radius R, the area of this circle can be computed as:

A = pi*R^2

where pi = 3.14

And the circumference is:

C = 2*pi*R

and we know that this is equal to 32 in, then:

32in = 2*pi*R

Now we can isolate R, and we get:

32in/(2*pi) = R

32in/(2*3.14) = R = 5.1 in

Then the area of the plate is:

A = 3.14*(5.1in)^2 = 81.67 in^2
