Can someone please help me with this ASAP

Answer 1

Answer: there are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies.

4/25 prefered digital copies
21/25 prefered hard copies

21 is more than 4.
The only one of the possible answers that imply that more people prefered hard copies was the third option. Therefore, "More grandparents prefer using a hard copy than a digital copy." is the most likely to be true.

50. It's 0.25 x 200. Or 1/4 of 200

What is the amplitude, period, and phase shift of f(x)=-5 sin(x+2 pie)-4

Answers

Step-by-step explanation:

For a wave:

y = A sin (2π/T x − φ) + B

A is the amplitude,

T is the period,

φ is the phase shift,

and B is the offset.

The given wave is:

f(x) = -5 sin(x + 2π) − 4

So the amplitude is -5, the period is 2π, and the phase shift is -2π.

I don't understand fractions. Please help me.

Fractions are one number over another number

As someone already said, fractions are one number over another number. But for this particular problem you would do 5 3/4 times 4 (since she jogged that many miles each day for four days) and then add that to the product of 2 3/5 times 7 (since she walked that many miles each day for seven days). You add them because it says what is the total number of miles Rachel walked and jogged last week. I then got 41 1/5 miles. So Rachel walked and jogged last week for 41 1/5 mikes.

Relationship B has a greater rate than Relationship A. The graph represents Relationship A.Which table could represent Relationship B?

A.
Time (weeks) -2- -5- -6- -9-
Plant growth (in.) -1.2- -3 -3.6- -5.4-

B.
Time (weeks) -2- -5- -6- -9-
Plant growth (in.) -1.4- -3.5- -4.2- -6.3-

C.
Time (weeks) -2- -5- -6- -9-
Plant growth (in.) -1.6- -4- -4.8- -7.2-

D.
Time (weeks) -3- -4- -6- -9-
Plant growth (in.) -1.5- -2- -3- -4.5-

Answers

The table that could represent Relationship B to have a greater rate than Relationship A is;

Table C

To find the rates of the various tables, we will use the formula;

Rate = Δy/Δx

Using the coordinates on the graph (4, 3) and (8, 6), we have;

Rate = (6 - 3)/(8 - 4)

Rate = 3/4

Rate = 0.75

For Table A;

From the graph, we can see the y-axis represents plant growth while the x-axis represents time.

Thus, using the coordinates (2, 1.2) and (5, 3), we have;

Rate = (3 - 1.2))/(5 - 2)

Rate = 0.6

For Table B;

Using the coordinates (2, 1.4) and (5, 3.5)

Rate = (3.5 - 1.4)/(5 - 2)

Rate = 0.7

For Table C;

Using the coordinates (2, 1.6) and (5, 4) gives;

Rate = (4 - 1.6)/(5 - 2)

Rate = 0.8

For Table D;

Using the coordinates (3, 1.5) and (4, 2) we have;

Rate = (2 - 1.5)/(4 - 3)

Rate = 0.5

The rate would be the gradient, defined by dy/dx.
For graph A this would be (6-3)/(8-4)= 3/4.
So any table showing a gradient of over 3/4 would have a faster rate.
Table A: (3-1.2)/(5-2)= 1.8/3= 0.6, less than 0.75
Table B: (3.5-1.4)/(5-2)= 2.1/3= 0.7, still less than 0.75
Table C: (4-1.6)/(5-2)= 2.4/3= 0.8.
This is a higher gradient than 0.75 in graph A. therefore table C shows a faster rate.
