The official all-time high temperature in Osoyoos, B.C., was 43°C in July 1998. The official all-time low temperature was –21°C

lesantik [10]

Answer: 64°C

Step-by-step explanation:

Official all-time high temperature = 43°C

Official all-time low temperature = –21°C

The difference between the two temperatures will be calculated by subtracting the low temperature from the high temperature. This will be:

= 43°C - (-21°C)

= 43°C + 21°C

= 64°C

The profits of life insurance companies A and B are normally distributed with the same mean. The variance of company B's profit

Lerok [7]

Answer:

23.58-th

Step-by-step explanation:

The standard deviation of company B's profit is:

$\sigma_B=\sqrt{2.25}\sigma_A$

Let X be the profit correspondent to the 14th percentile of company A's profit.

The z-score for 14th percentile of a normal distribution is roughly -1.08.

The z-scores for X in companies A and B are:

$-1.08 = \frac{X-\mu}{\sigma_a} \\z_B = \frac{X-\mu}{\sqrt{2.25}*\sigma_a}\\z_B=\frac{-1.08}{\sqrt{2.25}}\\z_B = -0.72$

The z-score for X in company B's profit distribution is -0.72, which corresponds to the 23.58-th percentile.

If each soda sells for $2.50, what is the expected daily total dollar amount taken in by the vendor from the sale of sodas?

Mariana [72]

Answer:

$34.38

Step-by-step explanation:

Y: A random variable that indicates the amount of money that the seller will receive.

p=2,50$

if x=0 → y=0.2,50=0$

if x=5 → y=5.2,50 = 12,5 $

if x=10 → y=10.2,50= 25$

if x=15 → y=15.2,50= 37,5$

if x=20 → y=20.2,50= 50 $

if x=25 → y=25.2,50= 62,5$

Y= { 0$ ; 12,5$ ; 25$ ; 37,5$ ; 50$ ; 62,5$ }

E(Y)= ∑Y.P(Y)

= 0.P(0)+12,5.P(12,5)+ 25.P(25)+ 37,5.P(37,5)+ 50.P(50)+ 62,5.P(62,5)

= 0.0,01+ 12,5.0,15+ 25.0,25+ 37,5.0,3+ 50.0,25+ 62,5.0,04

= 0 + 1,875 + 6,25 + 11,25 + 12,5 + 2,5

= 34,38$ expected value of the amount of money the seller receives.

Gennadij [26K]

Answer:

Step-by-step explanation:

(-1, 1) (1, -3)

(-3 - 1)/(1 + 1)= -4/2 = -2

y - 1 = -2(x + 1)

y - 1 = -2x - 2

y = -2x - 1

answer is A
