Answer:

1) The graph is as shown at the attached figure.

2) The line passes with (1,-3) and (2,-2)

Step-by-step explanation:

graph the line that passes with (3,-1) and has a y-intercept of -4

y-intercept is the value of y when x = 0

So, the line passes with (0 , -4)

The general form of the line  y = mx + c

Where m is the slope and c is y-intercept

given y-intercept = -4 ⇒ ∴ c = -4

using the other point to find m

So, when x = 3 , y = -1

So,  -1 = 3m - 4

Solve for m

3m = -1 + 4 = 3

m= 3/3 = 1

So, the equation of the line ⇒ <u>y = x - 4</u>

See the attached figure which represents the graph of the line

As shown at the graph the line passes through the points <u>(1,-3) and (2,-2)</u>

jeka57 [31]

Answer:

There is strong evidence that less than 87% of the orders are delivered in less than 10 minutes.

Decision rule: Reject the null hypothesis if (P-value < level of significance)

Test statistic z=-2.70

Decision: Reject the null hypothesis (0.003<0.010)

Step-by-step explanation:

In this question we have to test an hypothesis.

The null and alternative hypothesis are:

H_0: \pi\geq0.87\\\\H_a:\pi

The significance level is assumed to be 0.01.

The sample of size n=80 gives a proportion of p=61/80=0.7625.

The standard deviation is:

\sigma=\sqrt{\frac{\pi(1-\pi)}{N} }=\sqrt{\frac{0.87*0.13}{80} }=0.0376

The statistic z is then

z=\frac{p-\pi+0.5/N}{\sigma}=\frac{0.7625-0.87+0.5/80}{0.0376} } =\frac{-10125}{0.0376} =-2.70

The P-value is

P(z

The P-value (0.003) is smaller than the significance level (0.010), so the effect is significant. The null hypothesis is rejected.

There is strong evidence that less than 87% of the orders are delivered in less than 10 minutes.

Decision rule: Reject the null hypothesis if (P-value < level of significance)

Test statistic z=-2.70

Decision: Reject the null hypothesis (0.003<0.010)

Analyze the graph h(x).
Dominik [7]

Answer:

D h(x) = f(x)×g(x)

Step-by-step explanation:

h(x) has a wave with 2 changes in direction.

so, this needs to be an expression of the third degree (there must be a term with x³ as the highest power of x).

and that is only possible when multiplying both basic functions. all the other options would keep it at second degree (x²) or render it even to a first degree (linear).
