Answer:  The total distance for which the bike was tested is (x^2+5x)~\textup{miles}.

Step-by-step explanation:  Given that a sports company conducted a road test of a new model of a geared bike.

The test rider cycled (3x-2) miles on a flat road, (x^2-5) miles uphill and (2x+7) miles downhill.

We are to find the simplified expression that is equivalent to the total distance, in miles, for which the bike was tested.

The total distance for which the bike was tested is given by

D\\\\=(3x-2)+(x^2-5)+(2x+7)\\\\=3x-2+x^2-5+2x+7\\\\=x^2+5x.

Thus, the total distance for which the bike was tested is (x^2+5x)~\textup{miles}.

It would start like this:
(3x-2) + (2x - 5) + (2x+7)
= 7x
Sorry if it's wrong...

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 122 and standard deviation of 22
marin [14]

Answer: 4.27% of adults in the USA have stage 2 high blood pressure.

Step-by-step explanation:

Let x be a random variable that denotes a person with high blood pressure .

Given: Average blood pressure: \mu=122

Standard deviation: \sigma=22

Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher.

The probability that an adult in the USA have stage 2 high blood pressure:

P(x\geq160)=P(\dfrac{x-\mu}{\sigma}}\geq\dfrac{160-122}{22})\\\\=P(z\geq1.72)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z

Hence, 4.27% of adults in the USA have stage 2 high blood pressure.

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be​
Norma-Jean [14]

Answer:

270

Step-by-step explanation:

Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine

For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270

Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.

10*3=30 so we can say for this answer, the base is 3, and the height is 10.

10 tripled is 30, and 3 tripled is 9. 30*9=270

So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Hope this helpes!
