Answer:

theyre worth the same so twelve

Step-by-step explanation:

if you divide the amount youre spending then the amount youre buying you can get the price of each. therefore:

$9/12 cans = 0.75

$3/4 cans =0.75

so theyre the same amount just depends on how hungry you are

Solve 7 + x - 15 = -2 2/3 Please help!!! show your work please!

Margaret [11]

Firstly let’s make the -2 2/3 easier

-2*2/3= -4/3

Then we will move all the numbers to one side and keep the x on the other side. Remember when u move a negative from one side of the equal sign it changes to positive and if u move a positive it changes to a negative.

X= -4/3+15-7
=-4/3+8
=-4/3+24/3 (To add fractions the denominator has to be the same, and 24/3 is the same as 8)

X=20/3

Hopefully this helps

aleksklad [387]

Answer:the probability that exactly five customers make a purchase is 0.033

Step-by-step explanation:

The formula for binomial distribution is expressed as

P(x = r) = nCr × q^(n - r) × p^r

Where

p = probability of success

q= probability of failure

n = number of sample

From the information given,

39 percent of all customers who enter a store will make a purchase. It means that the probability of success, p = 39/100 = 0.39

The probability of failure q, would be 1 - p = 1 - 0.39 = 0.61

n = 6

The probability that exactly five customers make a purchase is expressed as

P(x = 5) = 6C5 × 0.61^(6 - 5) × 0.39^5

P(x = 5) = 6 × 0.61× 0.39^5 = 0.033

Please answer the circled questions below!

Anton [14]

Answer:

Step-by-step explanation:

1. The y-values in the table are constant, so the slope is 0. It is a horizontal line.

There is no x-intercept.

The y-intercept is (0, 1).

For lines in standard form, the intercepts can be found easily. The x-intercept is the value of x when y=0:

ax +0 = c

x = c/a . . . . x-intercept

Similarly, the y-intercept is the value of y when x=0:

0 +by = c

y = c/b

3. x-intercept = (-20/2, 0) = (-10, 0)

y-intercept = (0, -20/-5) = (0, 4)

4. x-intercept = (-6/1, 0) = (-6, 0)

y-intercept = (0, -6/-3) = (0, 2)

Plot these points and draw a line through them.

Jessica has 84.5 of fabric to make curtain

qaws [65]

Answer:

$10.8\ yd$

Step-by-step explanation:

The complete question is

Jessica has 84.5 yards of fabric to make curtains. She makes 6 identical curtains and has 19.7 of fabric remaining. How many yards of fabric does Jessica use per curtain?

Let

x-------> amount of yards of fabric that Jessica used per curtain

we know that

The length of 6 identical curtains plus the length of the fabric remaining, must be equal to the total yards of fabric'

The linear equation that represent this situation is

Solve for x

$6x=84.5-19.7\\6x=64.8\\x=10.8\ yd$
