An office supply store sells 12 rolls of tape for $29.88. At that rate, which proportion could be used to solve for c, the cost
kobusy [5.1K]

Answer:

$89.64

Step-by-step explanation:

First, you want to find your unit rate.

To do that, simply just divide what you know (cost/amount):

29.88/12

= 2.49

This means that one role of tape costs $2.49.

Now that we know that, you can simply just solve for value "c":

c = 2.49(36)

c = 89.64

Please help thank you :) brainliest?

Answer:

VXY = 38 degrees

YXW = 19 degrees

Step-by-step explanation:

The line XY is a angle bisector, meaning it divides the angle in half. YXW is the angle between the XY and XW lines. Which we know is 19 degrees.

Since we know the XY line divides the angle in half, we know VXW is also 19 degrees.

Therefore, VXW would be the sum of VXY and YXW: 19 + 19 = 38.

A baseball player has a batting average of 0.260. Suppose that you observe successive at-bats of the player and note for each at
Georgia [21]

Answer: Our required probability is 0.278.

Step-by-step explanation:

Since we have given that

Probability that a player has a batting average = 0.260

Probability of success = 0.260

Probability of failure = 1-0.260 = 0.74

Number of times at bat = 4

Probability that the player will get two or more hits in his next four times at bat is given by

P(X\geq 2)=P(X=2)+P(X=3)+P(X=4)\\\\P(X\geq 2)=^4C_2(0.26)^2(0.74)^2+^4C_3(0.26)^3(0.74+^4C_4(0.26)^4\\\\P(X\geq 2)=0.278

Hence, our required probability is 0.278.
