Gertrude sold 104 cars last year. There are 52 weeks in a year. What was the rate at which she sold cars?

If data set A has a smaller standard deviation than data set B, what would be different about their distributions?

Aleksandr-060686 [28]

Answer:

Data set B would have flatter distribution with more data in each tail.

Step-by-step explanation:

We are given the following in the question:

Data set A has a smaller standard deviation than data set B.

$\sigma_A < \sigma_B$

Standard Deviation:

It is a measure of dispersion of data.
It tells us about how much the data deviates around the mean.
It tells us about the overall deviation of the data from the mean.
The standard deviation is small when the data are all close to the mean showing less variation.
The standard deviation is larger when the data values are farther away from the mean, showing more variation.

Since data A has less standard deviation than data B, then data B has a flatter graphical representation as more of the data are present on the tails.

Eydin has two strips if stickers,A and B, of the same length.The length of each sticker is 1.2 cm. The stickers in each strip fo

deff fn [24]

Answer:

Each strip is 117.6 cm

Step-by-step explanation:

I created a proportion of hearts to others. On strip A there is 1 heart to 2 others and B there is 1 heart to 3 others. I added them and got a proportion of 2 hearts to 5 others for both. With a total of 56 hearts, I set up a proportion to determine the total stickers

2/5=56/x

When I cross multiply, I get 2x=280 and x=140

so for the 56 total hearts, I have 140 others. I added those to get the total stickers and got 196. I multiplied that by 1.2cm and got 235.2 cm for both. Since both are the same size, just divide that by 2 and get 117.6 cm each.

Find the scale factor

Mama L [17]

Answer:

C. 50

Step-by-step explanation:

The triangles are proportional and that is why you can find the scale factor. Set up a proportion (equivalent fractions). Set the proportion up with the corresponding sides together on thee top or the bottom of the proportion.

65 = 91

x 70

91x = 65 * 70

91x = 4550

91 91

x = 50

4. Calculate the product of 8/15, 645, and 1/3. A. 48/15 B. 48/30 C. 16/75 D. 18/15

DaniilM [7]

Answer:

645.866 or 646

Step-by-step explanation:

645.866 is the sum of 8/15+ 645/1 +1/3

1/3 = 0.333 + 8/15 = 0.533 = 0.866

645+ 0.866= 645.866

If we are asked to round these to units

we have 646
