Can someone help me figure this out!!!

Answers

Answer 1

Answers are 26=ED 36=DF 62=EF

Answer 2

Answer:

Basic Concept used:

Since D is the mid-point of EF,

ED will be equal to DF since D is in the middle of the line segment

We are given the following values for ED and DF

ED = 4x + 6 and DF = 7x - 9

Solving for x:

Since ED = DF (D is the mid point)

4x + 6 = 7x - 9

9 + 6 = 7x - 4x

15 = 3x

x = 5

Finding the values of ED , DF and EF:

we know that x = 5 (from the last section)

we are given the following values of the line segments:

ED = 4x + 6

DF = 7x - 9

EF (ED + DF) = (4x + 6) + (7x - 9)

Replacing x with 5 in each of these equations:

ED = 4(5) + 5 = 26

DF = 7(5) - 9 = 26

EF = (4(5) + 6) + (7(5)-9) = 26 + 26 = 52

Find the equation of a line parallel to -3x - 5y = 4 that contains the point (4,3). Write the equation in slope-intercept
form

Answers

9514 1404 393

Answer:

y = -3/5x +27/5

Step-by-step explanation:

Since we want a parallel line, we can use the same x- and y-coefficients to find the new constant in the given form:

-3(4) -5(3) = -12 -15 = -27

In the given form, the equation of the desired line is ...

-3x -5y = -27

Solving for y, we have ...

-5y = 3x -27

y = -3/5x +27/5

what is the mean (average) of 2,4,5,6,8

Answers

Answer:

Step-by-step explanation:

In order to figure out average, we need to add up all the numbers. So adding 2, 4, 5, 6, and 8 gives us 25. We now divide that total by the total number of terms we used to reach 25. So since we had 5 numbers, we divide 25 by 5 to get an average of 5.

Answer:

Step-by-step explanation:

To find mean. you just add all the numbers up and divide by the number of numbers (5).

2+4+5+6+8=25

25/5=5

Steven earns extra money babysitting. He charges $25.00 for 4 hours and $43.75 for 7 hours.

Enter an equation to represent the relationship. Let x represent the number of hours Steven babysits and y represent the amount he charges.

Answers

Answer:

An easy way to solve this problem is divide $25.00 by 3 or $43.75 by 7. This number represents the amount of money he makes for 1 hour. So with that in mind, the correct equation is:

$8.33 = y

What are the roots of the quadratic equation x²-81=0

Answers

Answer:

What are the roots of the quadratic equation x²-81=0

Answer:

x = ± 9

Step-by-step explanation:

Given

x² - 81 = 0 ( add 81 to both sides )

x² = 81 ( take the square root of both sides )

x = ± [tex]\sqrt{81}[/tex] = ± 9

Thus roots are x = - 9, x = 9

A florist has 80 flowers. She ties 3 flowers together in each bunch. If she makes as many bunches of 3 flowers as possible, how many flowers are left over?

26 bunches and 2 flowers.
Explanation: divide 80 by 3. You would get 26 and a little over. So, multiply 26 by 3 and you get 78. Subtract 78 from 80 and you have both answers.

A Karate club consists of 35 persons holding a black belt

rating), and 97 persons holding a purple belt (lowest rating).
What is the probability that a randomly-selected club member
holds a brown belt or a purple belt?
A) 0.238
B) 0.762
C) 0.687
D) 0.313

Answers

Answer:

Step-by-step explanation:

35+64+97=196 97+64=161 161/196=B

The probability that a randomly-selected club member holds a brown belt or a purple belt is 0.821 which is nearest to 0.762.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total number of person = 35+64+97 = 196

P(brown belt) = 64/196

P(purple belt) = 97/196

Probability that a randomly-selected club member holds a brown belt or a purple belt:

= 64/196 + 97/196

= (64+97)/196

= 161/196 = 0.821

Thus, the probability that a randomly-selected club member holds a brown belt or a purple belt is 0.821 which is nearest to 0.762.

The standard deviation from the National Health and Nutrition Survey is 1.29 hours. What is the variance (rounded to the hundredth place) ?

Answers

Answer:

variance = 1.66 hours

Step-by-step explanation:

It is given that,

The standard deviation from the National Health and Nutrition Survey is 1.29 hours.

We need to find the variance. We know that the relationship between the variance and the standard deviation is given by :

[tex]\text{Variance }=\text{standard deviation}^2\\\\\text{Putting all the values, we get :}\\\\\text{Variance }=(1.29)^2\\\\\text{Variance }=1.664\ \text{hours}[/tex]

Variance = 1.66

So, the variance is 1.66 hours.

Step by-step explanation:

When you have an even number of negative numbers in an equation, the answer will always be positive. When there's an odd number of negative numbers, the answer will be negative. For a problem like this, you can ignore the negative signs and focus on the numbers. 25+35 is 60, so Sally owes Alex 60 dollars.
