The recorded frequency for the interval 70 - 79 is incorrect, option C is correct.
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We can find the frequency for each interval by counting the number of data points that fall within each range.
There are no values between 10 and 19, so the frequency of 1 for the interval 10-19 is correct.
Similarly, there are no values between 50 and 59 or between 60 and 69, so the frequencies of 4 for the intervals 50-59 and 60-69 are correct.
when we count the values between 40 and 49 the range is 5 which is correct.
when we count the values between 70 and 79, we see that there are 3 value in this range, not 2 as listed in the frequency table.
Hence, the recorded frequency for the interval 70 - 79 is incorrect.

It's C I took the quiz
First will make the fraction is easier by turning it into 6/8 but because we’re halving it the we only halve the numerator, so it’s 3/8.
If this can’t be understood I’d gladly help elaborate
In 2003, 0.219 of the people in the United States were younger than 15 years old. Write the fraction with a denominator of one.
Answer: The decimal 0.219 can be converted to fraction by multiplying and dividing 0.219 by 1000. Therefore, we have:
Therefore, can be written as
Answer:
y intercept is -23
Step-by-step explanation:
Here we are given three coordinates and are asked to find y intercept of the line passing through these points.
We thus find the equation of this line by two point form
the form says
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
Here (x1,y1) = ( -36 , 1 )
and (x2,y2) = ( 13,-54)
Substituting the values we get
(y-1)(x+36)=(1-13)/(-36-(-54))
(y-1)(x+36)=(-12)/(-36+54)
(y-1)(x+36)=(-12)/(18)
y-1=-2/3 ( x+36)
In order to determine the y intercept we are required to leep x = 0 in above equation and solve for y
y-1 = -2/3 (0+36 )
y-1= (-2/3) x (36 )
y-1 = -2 x 12
y-1 = -24
adding 1 on both hand sides
y = -24 +1
y=-23
x^{2} + 13x +36
