Which of the following solution sets represent the inequality 3-1/2x ≥10
Hatshy [7]

Answer: x ≤ -14

Step-by-step explanation:

3 - \frac{1}{2}x ≥ 10

1) You want to subtract 3 from both sides of the equation: 3 - \frac{1}{2}x ≥ 10

                                                                                               -3           -3

                                                                                          ------------------------

2) Once you subtract 3 from both sides of the equation you'll be able to cancel out 3-3.

3) After, you'll be left with; -\frac{1}{2}x ≥ 7

4) You'll then want to divide both sides by -\frac{1}{2} to isolate x.

5) Divide 7 by -\frac{1}{2}

6) X ≥ -14, but then you'll want to flip the inequality since you divided by a negative.

7) X ≤ -14

Umnica [9.8K]

The 90th percentile is 1.2816 standard deviations from the mean. That tells you the standard deviation is ...

... (40 in - 38 in)/(1.2816) ≈ 1.56 in

The standard deviation for height for 4-year olds seems to be 1.56 inches.

The ratio of black marker in a box to blue markers in a box is 3:5. If there are 10 more blue markers than black markers,how man
fiasKO [112]

Answer:

Total = 40

Step-by-step explanation:

Given

Black:Blue = 3:5

Blue = 10 + Black

Required

Determine the total number of markers

First, we need to determine the ratio of black to blue such that

Blue = 10 + Black

Black:Blue = 3:5

Multiply the ratio by 5

Black:Blue = 3 * 5 : 5 * 5

Black:Blue = 15 : 25

By direct comparison:

Black = 15

Blue = 25

The above shows that:

Blue = Black + 10

So:

Total = Black + Blue

Total = 25 + 15

Total = 40
