Answer:

she buys half a pound and we need to know how much she spends.

If 1 full pound is $3, we need to half that.

What's half of 3?

1.5

So that means that a half pound of berries costs:

$1.50

Answer:

$1.50

Step-by-step explanation:

if one pound of boysenberries is $3, and we want to find the price of half a pound, simply divide 3 in half.

3/2 = 1.50

so, 1/2 lb of boysenberries is $1.50.

Solve the system by substitution. y = 5x y = 9x + 8

Ymorist [56]

Answer:

(-2,-10)

Step-by-step explanation:

So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):

5x=9x+8

Subtract 5x from both sides:

0=4x+8

Subtract 8 from both sides:

-8=4x

Divide both sides by 4:

x=-2

If x=-2, then we can just plug it back into the first equation:

y=5(-2)

Simplify:

y=-10

(6x²-x-1)/(x-1) How do I simplify this so it is not divided by anything?

a_sh-v [17]

Simplify:

The equation is already simplified =====> (6x² - x - 1)/(x - 1)

Solve:

Solution (6x² - x - 1)/(x - 1) =======> 6x + 5 + 4/x - 1

Steps:

Apply Long Division on:

(6x² - x - 1)/(x - 1)

Divide:

(6x² - x - 1)/(x - 1):

(6x² - x - 1)/(x - 1) = 6x + 5x - 1/x - 1

= 6x + 5x - 1/x - 1

Divide:

5x - 1/x - 1

= 5 + 4/x - 1

Answer ======> 6x + 5 + 4/x - 1

Hope that helps!!!!! : )

Assume the random variable x is normally distributed with mean u = 90 and standard deviation o=5. Find the indicated probability

Setler79 [48]

Given:

Let the random variable x is normally distributed with mean $\mu=90$ and $\sigma=5$

We need to determine the probability of $P(X$

Probability of $P(X$ :

The formula to determine the value of $P(X$ is given by

$Z=\frac{X-\mu}{\sigma}$

Thus, we have;

$P(X$

Simplifying, we get;

$P(X$

Using the normal distribution table, the value of -2 is given by 0.0228

$P(X$

Thus, the value of $P(X$ is 0.0228
