Answer:

b = 1/2m

Step-by-step explanation:

Let:

b = beth's age
m = meg's age

The prompt tells us that Beth is half as old as Meg. Therefore, mathematically, b = 1/2m.

Which statements are true given the histogram? Check all that apply.

vova2212 [387]

Answer:

(a)The histogram is symmetrical. FALSE

(b) The histogram is evenly distributed. FALSE

(d) More texts were sent from 6 p.m.-8 p.m. than from 8 p.m.-10 p.m. FALSE.

(e)The peak from 4 p.m.-6 p.m. means that the highest number of texts was sent during this interval. TRUE

Step-by-step explanation:

(a)The histogram is symmetrical.

FALSE, as the histogram has no line of symmetry.

(b) The histogram is evenly distributed.

FALSE, the histogram is not evenly distributed as there is no data in the

10: AM to 3:00 PM slot.

TRUE, the data shows that the most texts were sent in afternoon and evening as it has the highest peaks in the given slot.

(d) More texts were sent from 6 p.m.-8 p.m. than from 8 p.m.-10 p.m.

The number of texts sent from 6 p.m.-8 p.m = 19

The number of texts sent from 8 p.m.-10 p.m = 29

But, 19 < 29

Hence, the given statement is FALSE.

(e)The peak from 4 p.m.-6 p.m. means that the highest number of texts was sent during this interval. TRUE, the highest peak indicates the highest number of texts sent in the given interval.

Which graph shows the following system of equations and its solutions? -0.1x-0.3y=1.2 and 0.2x-0.5y=2

Vera_Pavlovna [14]

Answer:

Option b is the correct answer as both the equations are true for given solution.

Step-by-step explanation:

Given equations are:

-0.1x-0.3y=1.2

0.2x-0.5y=2

We can observe each graph and find the point that is the solution and put the point in the equations to know if that point is the solution

For option A:

(0,4)

Putting x=0 and y = 4 in both equations

$-0.1(0)-0.3(4)=1.2\\0-1.2 =1.2\\-1.2 \neq 1.2\\0.2(0)-0.5(4)=2\\0-2 = 2\\-2 \neq 2$

This is not the correct answer as both equations are not true with this solution

For Option B:

(0,-4)

Putting x = 0 and y = -4 in both equations

$-0.1(0)-0.3(-4)=1.2\\0+1.2 = 1.2\\1.2 = 1.2\\0.2x-0.5y=2\\0.2(0)-0.5(-4) = 2\\2 = 2$

Both equations are true for (0,-4) hence it is the solution of the system.

For Option C:

(4,0)

$-0.1(4)-0.3(0)=1.2\\-0.4-0 = 1.2\\-0.4 \neq 1.2\\0.2x-0.5y=2\\0.2(4)-0.5(0) = 2\\0.8 \neq 2$

Not true for both equations

Hence,

Option b is the correct answer.

Which decimal makes the comparison true? 7.68 > ______ a. 8.81 b. 8.68 c. 7.86 d. 7.56

Ostrovityanka [42]

Answer:

D. 7.56

Step-by-step explanation:

First we can see it has a less than symbol meaning whatever we put has to be less than the first number.

So the only number less than 7.68 is 7.65!
