When there is no traffic, it takes Rina 4 hours to get from Boston to New York. Once, Rina started her trip to New York at a speed of 60 mph, but after 2 1/3 hours of driving she stopped for 40 minutes. She had to drive at a speed of 45 mph for the rest of her trip. How long was her trip?
The whole trip was 0.185 Km or 185 m long.
What is speed ?Speed is the time rate at which an object is moving along a path.
Given:
For 7/3 hours speed is = 60 mph = 0.06 kmph
For 40 minutes or 2/3 hours = 0 mph
for 1 hours = 45 mph or 0.045 kmph
The total distance she travels
= 7/3*0.06+ 2/3*0+ 1*0.045

The height of female students in Cromartie High is normally distributed. If 95% of females are
between 57.6 and 70.4 inches tall centered about the mean, find the average height and standard
deviation for female students at Cromartie High.
Using the Empirical Rule, it is found that the mean is of 64 inches and the standard deviation is of 3.2 inches.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.The normal distribution is symmetric, hence the mean is given by:
M = (57.6 + 70.4)/2 = 64.
57.6 is two standard deviations below the mean, hence the standard deviation is found as follows:
57.6 = 64 - 2s.
2s = 6.4
s = 3.2.

What is 10 to the power of 3.
I would like to thank everyone that asked and answered questions I was stuck on. I graduated last week and couldnt have done it without Brainly.
Answer:
1000
Step-by-step explanation:
Hello!
10³ can be expanded to 10 x 10 x 10
Multiplying it out, we get 1000.
When multiplying by 10 you basically add a zero to the end, so we add 3 zeroes in total, which gives us 1000.
ExponentsWarning! [tex]x^y[/tex] is not [tex]x*y[/tex]. A very common error.
Instead, picture it as we are multiplying "x" by itself for "y" number of times.

To determine the equation of a circle, use the standard form of a circle (x - h)² + (y - k)² = r² where,
(h, k) is the center; andr is the radiusSubstitute the values of the center and radius to the standard form.
Given:
(0, 0) - center
2 - radius
(x - h)² + (y - k)² = 2²(x - 0)² + (y - 0)² = 4x² + y² = 4Answer:

Answer: x = 103
Step-by-step explanation:
this is a 90 degree angle indicated by the box in the corner of the angle.
90 degree angles total 90 degrees.
X - 15 + 2 = 90
move the numbers to the other side of the equal sign to isolate the X
by doing the opposite
x = 90 + 15 -2
x = 103
check your work, X - 15 + 2 = 90
103 - 15 + 2 = 90

Step-by-step explanation:
Which of the following functions best fits the data shown in the scatterplot below? y=100x+2y is equal to 100 x plus 2 y=20x2+10y is equal to 20 x squared plus 10 y=4x+8y is equal to 4 to the x th power plus 8 y=2x+5y is equal to 2 to the x th power plus 5
The equation of the scatter plot is (a) y = 100x + 2
How to determine the equation of the scatterplot?The line of best fit of the scatter plot passes through the points
(x,y) = (0,2) and (1,102)
Start by calculating the slope using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{102 - 2}{1 - 0}[/tex]
m = 100
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = 100(x -0) + 2
Evaluate
y = 100x + 2
Hence, the equation of the scatter plot is (a) y = 100x + 2

Two balls are drawn without replacement from a box containing 2black and 3 red balls. What is the probability of drawing a black ball on the second draw? Draw a tree diagram
The probability that the second ball drawn is black is 4/10 = 2/5
How to find the probability?
There are two cases. The case where the first ball is red is the first one.
The probability of drawing a red ball is equal to the quotient between the number of red balls and the total number of balls.
p = 3/5
Then, the probability of drawing a black ball in the second attempt is computed in the same way, but because we already drew a ball, now the total number of balls is 4, so we have:
q = 2/4 = 1/2.
So the joint probability is:
P = (3/5)*(1/2) = 3/10.
Then we have the case where both balls are black, the probabilities now are:
p = 2/5
q = 1/4
So the joint probability is:
P = (2/5)*(1/4) = 1/10
The total probability is the sum of the two above:
probability = 3/10 + 1/10 = 4/10.
The probability that the second ball drawn is black is 4/10 = 2/5

The height of the other book is 2 3/4 inches.Step-by-step explanation:
From the information,we get:
Two stacks of books together are = 7 1/2 inches tall.
One stack is given,that is = 4 3/4 inches.
To Find:
The height of the other.Solution:
Let us assume that the other height of the book be x.
Then the equation will be:
[tex] 4\cfrac{3}{4} + x = 7\cfrac{1}{2} [/tex]
Solve for x to get the other book's height.Convert the mixed fractions to fractions:
[tex] \implies \: \cfrac{19}{4 } + x = \cfrac{15}{2} [/tex]
Subtract 19/4 from both sides:
[tex] \implies \: x + \cfrac{19}{4} - \cfrac{19}{4} = \cfrac{15}{2} - \cfrac{19}{4} [/tex]
[tex] \implies \: x = \cfrac{11}{4} =\boxed{ 2 \cfrac{3}{4} \rm \: inches}[/tex]
Hence, we can conclude that:
The height of the other book is 2 3/4 inches.
