The temperature starts at 50°, then it slowly increases. Next it increases quickly, then it stays the same temperature for an hour. And finally the temperature slowly decreases.

The 1st graph is your answer(top left)

It is not the 2nd graph (top right) because the temperature stays at 50° for 2 hours, than decreases, which does not match the description.

It is not graph 3 (bottom left) because it increases quickly, than stays the same for 4 hours.

It is not graph 4 (bottom right) because the graph is decreasing most of the time

The top left graph is the only one correct. It rises up slowly then faster, and then stays constant for an hour, then decreases.

Point B is on line segment AC. If AB = x + 6, BC = x + 8 and AC = 10, then find the value of x.
kumpel [21]

Step-by-step explanation:

this simply means that the sum of both short segments must be the same as the length of the whole line.

so,

x + 6 + x + 8 = 10

2x + 14 = 10

x + 7 = 5

x = 5 - 7 = -2

how does the appearence of a histogram change when u use many small intervals then when you use a few large intervals
vampirchik [111]
If you're using a few larger intervals, then your histogram looks more stocky. If you imagine drawing one, it's because you're adding more values into the same category which can make the difference between two intervals much more noticeable. If you're using smaller intervals, however, you can much more accurately assess the difference between two different intervals. For that reason, the transition between one and another interval would look much more 'fluid'.

Softa [21]

Answer:54

Step-by-step explanation:

Pentagon has 5 sides

n=5

Sum of interior angles=180(n-2)

Sum of interior angles=180(5-2)

Sum of interior angles=180x3

Sum of interior angles=540

Size of each interior angle =540/n

Size of each interior angle =540/5

Size of each interior angle=108

x=108/2

x=54

According to the data, the mean quantitative score on a standardized test for female college-bound high school seniors was 500.
Sveta_85 [38]

Answer:

6.68% of the female college-bound high school seniors had scores above 575.  

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 50

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(scores above 575)

P(x > 575)

P( x > 575) = P( z > \displaystyle\frac{575 - 500}{50}) = P(z > 1.5)

= 1 - P(z \leq 1.5)

Calculation the value from standard normal z table, we have,  

P(x > 575) = 1 - 0.9332= 0.0668 = 6.68\%

6.68% of the female college-bound high school seniors had scores above 575.
