answer
(x+7)^2 + (y-4)^2 = 64
set up equation
the equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where h is the center x coordinate and k is the center y coordinate
values
from the point (-7,4) we know that h = -7 and k = 4
since the radius is 8, r^2 = 8^2 = 64
plug in values
now that we have all the values, we plug them into (x - h)^2 + (y - k)^2 = r^2
(x - h)^2 + (y - k)^2 = r^2
(x - (-7))^2 + (y-4)^2 = 64
(x+7)^2 + (y-4)^2 = 64
there is no drawing how should I do
-5/3 can be turned to a mixed number =-1 2/3
So can 18/11 = 1 7/11
10/4 = 2 2/4 or 2 1/2 simplified
And -3/3 as 1
This may make it easier to graph own the number line
Options
A. The number of cars passing through the intersection in one hour
B. The number of pedestrians crossing the intersection in one hour
C. The number of bicyclists crossing the intersection in one hour
D. The number of food trucks that park within four blocks of the intersection
E. The number of minutes for a car to get from the intersection to the administration building
Answer:
The number of minutes for a car to get from the intersection to the administration building
Step-by-step explanation:
A variable is said to be discrete if and only if it has a countable number of values. While a variable is said to be continuous if it can take infinitely many values.
Option a to d contains discrete variables (1 hour) and (4 blocks), so they can't be regarded as the right option. 1 hour and 4 blocks are specified values and they can't take any other fraction of values aside 1 and 4 respectively.
Looking at option e, the variable, number of minute as stated in this option is a continuous variable. This is so because at any two interval of minutes, fractions and lots of a minute can always be recorded by the engineer to study the traffic flow
Using the normal distribution, it is found that she scores less than 128 in 28.1% of her games.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the mean and the standard deviation are given, respectively, by 
.
The proportion of games in which she scores less than 128 is the <u>p-value of Z when X = 128</u>, hence:
Z = -0.58
Z = -0.58 has a p-value of 0.281.
She scores less than 128 in 28.1% of her games.
