Answer:

5/4

Step-by-step explanation:

The problem tells us that 4 equal sections stacked together is 5 feet tall. Thus, we have to find how tall each section is while all sections are equally tall. So, we have to divide 5 feet by 4 equal sections, which is just 5 divided by 4, which is just 5/4 feet tall.

A rectangle has a a perimeter of 68 ft. The length and width are scaled by a factor 1.5.

The perimeter of the resulting rectangle is ___ ft.

Answers

Answer and Step-by-step explanation:

Answer and Step-by-step explanation:

Here is the equation for finding the sides (just to show):

68 = (2L + 2W)

We multiply L and W by 2 because there are two of the lengths and 2 of the widths.

Now, we add the scale factor to the outside, but on both sides of the equation.

68 × 1.5 = 1.5(2L + 2W)

Multiply 68 by 1.5.

102 = 1.5(2L + 2W)

The answer is 102.

The perimeter of the resulting rectangle is 102 ft.

Find the probability of rolling divisors of 8.

Answers

I’m assuming it’s referring to two regular dice? (2 dice with numbers 1-6 labeled)
The divisors of 8 are 1,2,4, and 8
I’m interpreting as rolling the number on the die not the sum of the dice
So it’s 3/6 numbers on the die or 1/2 and there are two dice to rolling a divisor of 8 on both dice is 1/2 x 1/2 or 1/4

In a class of 30 students, 12 have a cat and 19 have a dog. There are 6 students who
do not have a cat or a dog. What is the probability that a student chosen randomly
from the class has a dog?

Answers

Answer:

19/30

Step-by-step explanation:

30 students

12 have cat , 19 have dog , 6 no cat or dog

P dog = 19 have dogs/30 students total = .633333...

The likelihood that a randomly selected student in the class owns a dog is 19/30.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Let A be the event that a student has a dog. Then, the number of students having a dog is 19, and the total number of students is 30.

The number of students having neither a cat nor a dog is 6. Therefore, the number of students having at least a cat or a dog is:

12 (number of students having a cat) + 19 (number of students having a dog) - 6 (number of students having neither a cat nor a dog) = 25

Thus, P(A) = number of students having a dog / total number of students = 19/30.

Therefore, the probability that a student chosen randomly from the class has a dog is 19/30.

The median for Set A is greater than the median

for Set B.

The ranges for both sets are equal

The medians for both sets are equal.

Answers

Answer:

The median for Set A is greater than the median

for Set B.

Step-by-step explanation:

From the boxplot attached, we can deduce the following :

Median (vertical line in between the box on a boxplot).

Median, set A = 30

Median, set B = 29

Range = (Maximum - Minimum. Value)

Set A :

Maximum = 35 ; Minimum = 21

Range = 35 - 21 = 14

Set B :

Maximum = 37 ; Minimum = 24

Range = 37 - 34 = 3

Hence, from the options, the only correct statement is The median for Set A is greater than the median for Set B.

Lines A and B are parallel
m<6 = [?]°

Answers

Answer:

Im pretty sure its 55

Step-by-step explanation:

So it adds to a 180 degree angle

When lines A and B are parallel m<6 (the measure of angle 6) is 55° .

If lines A and B are parallel and ∠4 and ∠6 are consecutive interior angles, then we can use the property that consecutive interior angles add up to 180°.

Given that ∠4 is 125°, we can substitute this value into the equation :

∠4 + ∠6 = 180°.

125° + ∠6 = 180°.

To find the measure of ∠6, we can subtract 125° from both sides :

∠6 = 180° - 125°.

∠6 = 55°.

Therefore, m<6 (the measure of angle 6) is 55°.
