Answer:
D
Step-by-step explanation:
Its D because integers and whole numbers cannot be fractions, while a rational number can. A, B, C, and D can all be simplified into whole numbers while 7/11 cant
What are the transformations on the following
function, f (x) = -2 log4 (x + 5) - 4?
Answer:
8
Step-by-step explanation:
= f (x) = -2 log 4 (x + 5) - 4
= 4 (-2 + 5) - 4
= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3
= So now you have 4 (3) - 4
= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.
= 4 (3) which is the same as 4 × 3 which is 12.
= then you do 12 - 4 which is 8.
= 8 is your answer.
I hope this helps.

find the value of x in each triangle. show your work on a separate piece of paper
Answer:
x = 70°
Step-by-step explanation:
the interior angle which is supplemental to 140° is 40°
the sum of the interior angles of any triangle is 180°
so:
180° = 40° + 2x
subtract 40° from each side of the equation:
2x = 140°
x = 70°

=) of the 35 seventh graders polled, 1/7 of them play a sport. How many do not play a sport?
a)5 students
C)25 students
B)14 students
D)30 students
Answer:
D
Step-by-step explanation:
the number of students who plays sport are 1/7 of 35 that means that there are 35/7 students play sport so there is only 5 of 35 students play sport
so number of students thatn dont play sport are 35 - 5 = 30
Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 65 inches and the
standard deviation is 3 inches, 68% of the population will have a height within
which range?
A. 59 inches to 71 inches
B. 53 inches to 77 inches
C. 62 inches to 68 inches
D. 56 inches to 74 inches
Answer:
C; 62 to 68 inches
Step-by-step explanation:
Here, we want to get the population range that is having a probability of 68%
From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%
From the question;
1 standard deviation above the mean is 65 + 3 = 68
1 standard deviation below the mean is 65-3 = 62
so the range of the height of the population is 62 to 68 inches

Solve the pair of simultaneous equations and leave the answer as a fraction in
its lowest term. 2x − 3 = y, x+ y= 8
Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3

Find the missing angle.
(look at the picture)
Answer: 45
Step-by-step explanation:
59 + 76= 135
180-135= 45
Answer:
m∠1 = 45 degrees
Step-by-step explanation:
All triangles have the interior angle of 180
to find the missing angle, take the known angles and add them together:
76 + 59 = 135
then take the sum and subtract it from 180:
180 - 135 = 45

Step-by-step explanation:
You drank 12 ounces of your 16 ounce Dutch Bros. What percent is LEFT?
Answer:
25% is left
Step-by-step explanation:
12oz is how much is consumed and 16-12+4 so 4oz remain and to convert that to a percent you do 4 divided by 16 which is 0.25 and to get the present age you multiple 0.25 by 100 to get 25% left
The percentage of Dutch Bros left is 25%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, You drank 12 ounces of your 16 ounce Dutch Bros.
Here, percentage left = Difference in ounce of Dutch Bros/Total quantity of Dutch Bros ×100
= (16-12)/16 ×100
= 4/16 ×100
= 25%
Therefore, the percentage of Dutch Bros left is 25%.

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
y= -2x +2
Step-by-step explanation:
The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.
To find the value of m, use the gradient formula below:
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]
[tex]m = \frac{6 + 4}{ - 5} [/tex]
[tex]m = \frac{10}{ - 5} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).
y= -2x +c
When x= 3, y= -4,
-4= -2(3) +c
-4= -6 +c
c= -4 +6
c= 2
Thus, the equation of the line is y= -2x +2.
