Answer:

Option C is correct.

The exponential grows at twice the rate of the quadratic.

Step-by-step explanation:

Slope(rate) is given by:

\text{Slope} = \frac{y_2-y_1}{x_2-x_1}

As per the statement:

An exponential function and a quadratic function are graphed below.

In the given interval: [0, 1]

In Exponential function  graph

Consider points (0, 1) and (1, 2)

then by definition  of slope we have;

\text{Slope} = \frac{2-0}{1-0} = \frac{2}{1} = 2

⇒Rate of exponential function is 2

In Quadratic function graph:

Consider points (0, 0) and (1, 1)

then by definition  of slope we have;

\text{Slope} = \frac{1-0}{1-0} = \frac{1}{1} = 1

⇒Rate of quadratic function is 1

⇒\text{Rate of exponential function} = 2 \cdot \text{rate of quadratic fucntion}

Therefore, the exponential grows at twice the rate of the quadratic.

A stationary store has decided to accept a large shipment of ball-point pens if an inspection of 17 randomly selected pens yield
Leno4ka [110]

Answer:

0.762 = 76.2% probability that this shipment is accepted

Step-by-step explanation:

For each pen, there are only two possible outcomes. Either it is defective, or it is not. The probability of a pen being defective is independent from other pens. So we use the binomial probability distribution 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.

17 randomly selected pens

This means that n = 17

(a) Find the probability that this shipment is accepted if 10% of the total shipment is defective. (Use 3 decimal places.)

This is P(X \leq 2) when p = 0.1. So

P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)

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

P(X = 0) = C_{17,0}.(0.1)^{0}.(0.9)^{17} = 0.167

P(X = 1) = C_{17,1}.(0.1)^{1}.(0.9)^{16} = 0.315

P(X = 2) = C_{17,2}.(0.1)^{2}.(0.9)^{15} = 0.280

P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.167 + 0.315 + 0.280 = 0.762

0.762 = 76.2% probability that this shipment is accepted

225 g flour
Pachacha [2.7K]
If she needs to use 225g of flour for each cake and wants to make 18 cakes she will need 4050g (225x18=4050) of flour but she only has 360g which is obviously not enough flour. For one cake she needs 75g of sugar and since she needs to make 18 cakes she needs 1350g (75x18=1350) of sugar. She only has 135g so it’s not enough.
