What might a model for 3 Times 3/5 look like? How many fifths would be shaded in all?

1 answer:

5 0

It's a bit hard to do a model on here, but I'll try to represent it. Note that the "a"s are the shaded parts and the "b"s are the non-shaded parts.

a a a
a a a
a a a
b b b
b b b

There are 9/15 shaded.

In Mary's first math test she scored 87%. The mean and standard deviation for the class were 71% and 18% respectively. In her se

Answer:

Step-by-step explanation:

Since your population are the students in math class, you can use the z-score formula $z=(x-\mu)/\sigma$ in order to comparing the two math test scores. Where $\mu$ is the mean for the class, $\sigma$ is the standars deviation and x is Mary score.

For the first test $\mu=.71 , \sigma=.18,x=.87$ , so , $z_{1} = (.87-.71)/(.18)=.88$ .

For the second test $\mu=.53 , \sigma=.14,x=.66$ , so , $z_{1} = (.66-.53)/(.14)=.93$

Mary do better in the second test, relative to the rest of the class (because $.88 \leq .93$ , it means the second score is nearer to the mean score of the class than the first one )

1. Julie went to the store to buy a pair of pants. The pants

Lostsunrise [7]

Answer:

Step-by-step explanation:

1) Let x represent the sale price.

normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is

25/100 × 39.95 = 9.9875

Sale price = 39.95 - 9.9875 = $29.9625

2) number of games played by the tigers is 11 + 4 = 15

Percentage of games won is

11/15 × 100 = 73.3%

number of games played by the cubs is 10 + 3 = 13

Percentage of games won is

10/13 × 100 = 76.9%

3) increase in stock price = 61.5 - 52.63 = $8.87

Percentage increase = 8.87/52.63 × 100 = 16.85%

4) if 28 percent of seven graders went

to a movie theater over the weekend and there are 800 students in the seventh grade, then the number of seven graders that saw

the movie is

28/100 × 800 = 224

in a game of tug of war, your team changes -1 3/10 feet in position every 10 seconds. What is your change in position after 30 s

Gelneren [198K]

Answer:

$-3\frac{9}{10} ft$

Step-by-step explanation:

Given that the change is -13/10 in 10 seconds

Here, you can write this statement as;

10s = -13/10

30s=?----------------perform cross-multiplication

(-13/10 * 30 ) /10

$=\frac{-13}{10} *\frac{30}{10} =\frac{-39}{10} \\\\\\=-3\frac{9}{10}$

Can someone help me find the maximum or minimum value?

Elden [556K]

Answer:

(c) Minimum value is -16.

Step-by-step explanation:

This will have a minimum value because the leading coefficient is positive.

We can find the minimum value by converting the function to vertex form:

f(x) = x^2 + 4x - 12

f(x) = (x + 2)^2 - 4 - 12

f(x) = (x + 2)^2 - 16.

The minimum value is -16.

So when you draw the graph the turning point is at (-2, -16).
