Your state charges 5% sales tax on nonfood items. You're buying a light bulb for $3.00, cereal for

1 answer:

6 0

We first add the tax to the non-food items. We have ($3.00+$.50)*1.05=($3.50)*1.05=$3.675 (Which can be rounded up to $3.68, since we can't have a fraction of a cent).

Now, we add the cost of the food to $3.68. As a result, we have $3.68+$2.50=$6.18 as the total bill.

An experimenter conducted a two-tailed hypothesis test on a set of data and obtained a p-value of 0.44. If the experimenter had

Lyrx [107]

Answer:

Correct option is (C).

The possible value of the p-value for a one-tailed test are 0.22 and 0.78.

Step-by-step explanation:

The p-value is the probability of acquiring a result as extreme as the observed result, assuming the null hypothesis statement is true.

The p value of a test is:

Left-tailed test: $P(TS$

Right-tailed test: $P(TS>ts) = 1- P(TS$ .

Here,

TS = Test statistic

ts = computed value of the test statistic.

The two-tailed p-value is: $2P(TS$ or $2P(TS>ts)$ .

The p-value of the two tailed test is, 0.44.

Compute the p-value for one-tailed test a follows:

For a left-tailed test:

$2P(TS$

For a right-tailed test:

$P(TS>ts) = 1- P(TS$

Thus, the possible value of the p-value for a one-tailed test are 0.22 and 0.78.

The correct option is (C).

Erica has already knit 5 centimeters of scarf, and can knit 1 centimeter each night. Write an equation that shows the relationsh

ollegr [7]

Answer:

5+x=y

Step-by-step explanation:

If she has already knit 5 cm you will always have to factor that in. If x is the number of nights adding the number of nights she does 1 cm of knitting will give you the length she has knit so far (y). I hope this helped! Good luck

Find the equation of the line that has a slope of 2

alina1380 [7]

Answer:

The equation in the point-slope form will be:

$y-(-8) = 2 (x-5)$

Step-by-step explanation:

The point-slope form of an equation is written as:

$y-y_1=m\left(x-x_1\right)$

where m is the slope, and (x₁, y₁) is a point on the line.

Now, we will substitute the values of m and (x1, y1) in the given equation. Here,

m=2

and

(x1, y1) = (5, -8)

x1 = 5

y1 = -8

$y-y_1=m\left(x-x_1\right)$

$y-(-8) = 2 (x-5)$

Therefore, the equation in the point-slope form will be:

$y-(-8) = 2 (x-5)$
