Answer:

Step-by-step explanation:

Since the graph hits 0 at x = 0, your y intercept is 0.

The graph is decreasing which means you have a negative slope.

They gave you a coordinate so use it to find the slope.

$\frac{1-0}{-3-0} = \frac{-1}{3}$

That's your slope.

C is the correct answer.

Let's first take a look at function G. From the first to second row, the x-value increases by 2, and the y-value increases by 8.

Thus, function G has a rate of change of $8/2$ , or 4.

In function H, there is a "2" before the "x", which means function H has a rate of change of 2.

Thus, the statement that is true is:

Function G has a rate of change of 4, and function H has a rate of change of 2

Let me know if you need any clarifications, thanks!

The circumference of the top rim of the cone-shaped paper cup is 8.66 inches. Find the least amount of paper that can form the c

navik [9.2K]

Answer:

15.59 square inches

Step-by-step explanation:

In the required given diagram, the slant height of the cone was given as 3.6 inches.

The least amount of paper required would be equal to the curved surface area of the cone.

curved surface area of a cone = $\pi$ rl

where r is the radius and l the slant height.

circumference of the top rim = 8.66 inches

circumference = 2 $\pi$ r

⇒ 8.66 = 2 $\pi$ r

4.33 = $\pi$ r

r = 4.33/ $\pi$

curved surface area = $\pi$ x 4.33/ $\pi$ x 3.6

= 4.33 x 3.6

= 15.588 square inches

Thus, the least amount of paper that can form the cone shaped cup is 15.59 square inches.

A clear file box shaped like a rectangular prism is modeled below. The shaded part represents one base of the box. A formula for

IRINA_888 [86]

Answer:

C. B = (19)(14)

Step-by-step explanation:

Given:

length (l) = 19 in.

width (w) = 14 in.

height (h) = 11 in.

Formula for volume of the rectangular prism = Bh

Base area (B) = l*w

Base area (B) = (19)(14) in.²

Formula for finding base area: B = (19)(14)

The lifetime of a battery in a certain application is normally distributed with mean μ = 16 hours and standard deviation σ = 2 h

DaniilM [7]

Answer:

Probability that a battery will last more than 19 hours is 0.0668.

Step-by-step explanation:

We are given that the lifetime of a battery in a certain application is normally distributed with mean μ = 16 hours and standard deviation σ = 2 hours.

Let X = lifetime of a battery in a certain application

So, X ~ N( $\mu=16,\sigma^{2} =2^{2}$ )

The z-score probability distribution for normal distribution is given by;

Z = $\frac{ X -\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = mean lifetime = 16 hours

$\sigma$ = standard deviation = 2 hours

The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

So, the probability that a battery will last more than 19 hours is given by = P(X > 19 hours)

P(X > 19) = P( $\frac{ X -\mu}{\sigma}$ > $\frac{19-16}{2}$ ) = P(Z > 1.50) = 1 - P(Z $\leq$ 1.50)

= 1 - 0.9332 = 0.0668

Now, in the z table the P(Z $\leq$ x) or P(Z < x) is given. So, the above probability is calculated by looking at the value of x = 1.50 in the z table which has an area of 0.9332.

Hence, the probability that a battery will last more than 19 hours is 0.0668.
