Answer:

Saints; they have a larger mean value of about 14 points

Step-by-step explanation:

The mean is the best to use here since we are trying to determine the best overall record. Adding up all of the scores for the Saints will get you a total of 210, which then has to be divided by the number of numbers, which is 15. The Saints' mean is larger than the mean for the Cowboys, making your answer "Saints; they have a larger mean value of about 14 points".

Answer:

(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Step-by-step explanation:

The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Answer: divide and multiply

Step-by-step explanation: using PEMDAS, the first steps must be inside of the parenthesis; going further, the nex steps (multiplication and division) are interchangeable, so you do whichever comes first (in this case, -24 / 6 followed by that times 2)

Answer:

55.1 ft

Step-by-step explanation:

4 + 4 + circumference of the circle

Formula for circumference of a circle is 2 · π · radius, but can also be written as π · diameter

4 + 4 + (15 · π)

4 + 4 + (15 · 3.14)

4 + 4 + 47.1

8 + 47.1

55.1

The time needed for the rocket to be 30 feet of the ground is given as follows:

t = 9.6 seconds.

The quadratic function giving the rocket's height after t seconds is given as follows:

h(t) = -16t² + 150t + 70.

The rocket will be 30 feet of the ground when:

h(t) = 30.

Hence:

-16t² + 150t + 70 = 30

16t² - 150t - 40 = 0.

The coefficients of the quadratic function are given as follows:

a = 16, b = -150, c = -40.

Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

t = 9.6 seconds.

Place the dot in the middle of -1 and -2!

Step-by-step explanation:

You have to add 2 -2 2/6 and 5/6 that will get you -1 3/6. Then you have to find where it goes. If you would simplify the number you would get -1 1/2. This means the dot would be placed in the middle of 2 numbers. Since it is 1 and 1/2 you would need to place it between -1 and -2.

To determine the scale factor used to dilate polygon ABCD to A′B′C′D′, we can compare the corresponding side lengths.

The distance between A(1, 1) and B(3, 1) is 2 units, and the distance between A′(3, 3) and B′(9, 3) is 6 units, so the horizontal side has been scaled by a factor of 6/2 = 3.

Similarly, the distance between A(1, 1) and D(1, 2) is 1 unit, and the distance between A′(3, 3) and D′(3, 6) is 3 units, so the vertical side has been scaled by a factor of 3/1 = 3.

Since both scaling factors are equal to 3, the overall scale factor used to dilate the polygon is 3. Answer: 3.

Answer:

Step-by-step explanation:

To find the interquartile range, we first need to find the values of the first and third quartiles.

The median of the data set is 4. To find the first quartile, we take the median of the lower half of the data set:

1 1 3 3 | 4 4 5 7 7

^

First quartile = 3

To find the third quartile, we take the median of the upper half of the data set:

1 1 3 3 | 4 4 5 7 7

^

Third quartile = 7

The interquartile range is the difference between the third quartile and the first quartile:

7 - 3 = 4

Therefore, the interquartile range of the data set is 4.

Answer: 200/7

Step-by-step explanation:

This creates 3 similar right triangle

you would put similar parts  on top and the similar parts on bottom of proportions.

ex.

[tex]\frac{hypotenuse}{short leg} = \frac{hypotenuse}{short leg}[/tex]

in your problem they gave the short legs and long legs of right triangel

The line that they share in middle of the triangle is the long leg for the triangle on right and it is also the short leg for triangle on left.

[tex]\frac{long leg}{short leg} =\frac{long leg}{short leg}[/tex]

[tex]\frac{x}{20} = \frac{20}{14}[/tex]

x=(400)/14 = 200/7

You could also make your proportion where

parts of 1 triangle = equivalent parts of the other

ex.

[tex]\frac{long leg from big triangle}{long leg from small triangle} = \frac{short leg big triangle}{short leg from small triangle}[/tex]

Answer:

D. None of the above.

Step-by-step explanation:

To evaluate the expression when x = 6, we substitute 6 for x in the expression:

2 - 3(x - 5)

= 2 - 3(6 - 5)

= 2 - 3(1)

= 2 - 3

= -1

Therefore, the value of the expression when x = 6 is -1.

So, the answer is D. None of the above.

Answer: none of the above

Step-by-step explanation:

When x = 6 We substitute 6 for x in the expression:

2 - 3(x - 5)

2 - 3(6 - 5)

2 - 3(1)

2 - 3

= -1

Answer:

3 6/8

Step-by-step explanation:

30÷8=3 6/8

8×3=24

30-24=6

Answer:

The mixed that represents 30/8 is --> 3 3/4

Step-by-step explanation:

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

30/8= 3.75 = 3

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:

30 - (8 x 3) = 6

Step 3: Our mixed fraction

We've now simplified 30/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

3 6/8

Step 4: Simplifying our fraction

In this case, our fraction (6/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 6 and 8 is 2.

We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.

6/2 = 3

8/2 = 4

When we put that together, we can see that our complete answer is:

3 3/4

Answer:

The correct answer:

y equals three halves times x (y = (3/2)x)

Answer: x-2 =4

Step-by-step explanation:

First of all you want to undo the multiplication. So what ever you do to one side you do to the other so divide 5 from both sides and you get x-2=4

Answer:

The answer for x-2=4

x=4+2;x=6

Step-by-step explanation:

5(x-2)=20

divide both sides by t

5(x-2)/5=20/5

(x-2)=4

x=4+2=6

Answer:

The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent

Step-by-step explanation:

By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.

85 ÷ 5 = 172

40 ÷ 5 = 48

125 ÷ 5 = 25

50 ÷ 5 = 10

Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent

Answer:

Choice C

Step-by-step explanation:

We first have to find the sum of the students.

85 + 240 + 125 + 50 = 500

Next, we have to find the percentage of each group of students for each group.

Users of Tweeter = 85 (17%)

Users of VidTok = 240 (48%)

Users of Headbook = 125 (25%)

Users of Picturegram = 50 (10%)

Therefore C is the answer

Answer:

Step-by-step explanation:

Answer:

Let's start by using variables to represent the ages of the three people:

Let L be Liz's age.

Let D be Debbie's age.

Let F be Freya's age.

From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:

L = (2/3)D

We also know that Debbie's age is half of Freya's age, so we can write:

D = (1/2)F

To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:

F = 2D

Now we can substitute this expression for F into the equation for Liz's age:

L = (2/3)D = (2/3)(1/2)F = (1/3)F

So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Answer:6 inches.

Step-by-step explanation: What is the radius of a circle with an area of 113.04 square inches?

Radius of the circle is of 3 inches.

Step-by-step explanation:

It is given that the area of the circle is 113.04,

Let the radius of the circle be of "a" units

=======================

From the properties of circle, we know : -

Area of circle = πr^2 , where r is the radius of the circle.

======================

Then, comparing the question with the identity :

= > πr^2 = 113.04 sq. inches

= > 3.14 x r^2 =  113.04 sq. inches

= > r^2 = 113.04 / 3.14 sq.inches

= > r^2 = 36 sq. inches

= > r = 6 inches

Hence,

r or radius of the circle is of 6 inches.
