Step-by-step explanation:
[tex]f(x) = \left \{ {{2x + 7; x<1 } \atop {10 - 5x; x \geq 1}} \right.[/tex]
Substitiute in "2" for "x".
Since "2" is greater than "1", then the second equation must be used.
Substitute in "2" of "x".
10 - 5x
10 - 5 * 2

Mr.Johnson is planning what to wear tomorrow. He has a white shirt, a plaid shirt, and a blue shirt. He has four pairs of pants to choose from. They are black, brown, gray, and white. If he chooses one shirt and one pair of pants, how any possibilities does r. Johnson have?
Answer:
Mr. Johnson has 12 possibilities.
Step-by-step explanation:
The information provided are:
Mr. Johnson has a white shirt, a plaid shirt, and a blue shirt.Mr. Johnson has four pairs of pants, black, brown, gray, and white.He chooses one shirt and one pair of pants.Compute the number of ways to select a shirt and a pair of pants as follows:

perimeter: 16, calculate
the value of x when the length
of the rectangle is 3x and the
hieght is x
Step-by-step explanation:
Perimeter = 16
length = 3x
height = x
P = 2L + 2H
16 = 2(3x) + 2(x)
16 = 8x
hence:
x = 2.

y+9 = -5x+10
y = -5x+1
a bakery sells 3642 pastries in 2010. The bakery sells 8422 pastries in 2015. write a linear model that represents the number y of pastries that thw bakery sells x after 2010.
Answer:
Step-by-step explanation:
x is number of years after 2010
y is number of donuts
we are given
A bakery sells 7196 donuts in 2010
So, when x=0 , y=7196
Let's assume
The bakery sells 9236 donuts in 2015
now, we can find slope
we can plug values
now, we can use point slope form of line
we can plug values
based on the graph, what are the rate of change and the y intercept of the line.
O the rate of change is 1/2 and the y-intercept is 1
O the rate of change is one and the y-intercept is 1/2
O the rate of change is 1/2 and the y intercept is -2
O the rate of change is 2 and the y intercept is 1
Answer:
The rate of change is 1/2 and the y-intercept is 1
Step-by-step explanation:
You can calulate the rate of change by picking two points on the graph and using the slope formula
(y2-y1)/(x2-x1)
so in this example you can use the points (2,2) represeting (x1,y1) and (4,3) representing (x2,y2)
When you plug into the slope formula you get:
(3-2)/(4-2) = 1/2 which is the slope.
The y-intercept is where the line intersects the y=axis and can be seen as the coordinate pair (0, #) where the # is the y intercept. From the graph you can see the y-intercept is 1, but you can aslo solve for the y-intercept using the slope-intercept equation:
y=mx+b
where b is the y-intercept and m is the slope.
so using a slope of 1/2 and a coordinate of (2,2) you get:
y-2=(1/2)(x-2)
y = (1/2x)-1+2
y = (1/2x) + 1
so now the equation is in slope-intecept form and you can see the slope is 1/2 and the y-intercept is 1
Jada gets a quarters from a change machine at an arcade. She receives 4 quarters for every
dollar bill, d, that she puts into the machine.
What variable is dependent and independent between The number of dollor bills which is d and the number of quarters which is q??
Answer:
The dollar bills d are the independent variable while the number of quarters q are the dependent variable
Step-by-step explanation:
Here, we want to state the variable that is dependent and the one that is independent
from the question, she has to put in dollars to get the quarters
so the number of quarters she gets is dependent on the number of dollars put into the machine
Thus, we can conclude that;
The dollar bills are the independent variable while the number of quarters q are the dependent variable
Independent variables are those who are not dependent on other variables. In contrast, their exists dependent variables whose value depends on some other variable(s)' value(s).
For given case, the number of dollar bills 'd' is independent variable with respect to variable 'q'.
The number of quarters 'q' is dependent variable.
What are independent variables?Independent variables are those who are not dependent on other variables for their evaluation.
What are dependent variables?Those variables whose value is decided by the values of other variables. This shows that the variable in consideration is dependent on other variables for its values, thus called dependent variable.
Which of 'd' or 'q' is dependent and independent?If you see it carefully, you'll see that the quarters received from the change machine is depending on how much dollar bills you're feeding to the machine.
Thus, the value of 'q' is dependent on the value of d.
But since d takes its value independent of q (it exists before q exists and doesn't need q to get its values), thus, d is not dependent on q or is independent variable with respect to q(i said "with respect to q" since d might be dependent on some other variable which we do not know right know)
Thus:
The variable 'q' is dependent variable (depends on d)
The variable 'd' is independent variable with respect to 'q.

According to the WHO report, girls who are 2-years old have a mean head circumference of 47.18cm with a standard deviation of 1.40 cm. A two year old girl with Down's syndrome has a head circumference of 44.5 cm. Children with Down's syndrome typically have smaller heads, so this is not surprising. 1. Relative to the WHO data, what is this girls z-score? What does the z score tell us? 2. Using the WHO data in a normal model, what percentage of the girls has a head circumference that is smaller than the girl with Down's Syndrome?
Answer:
1. z = -1.91429
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. 2.7792%
Step-by-step explanation:
1. Relative to the WHO data, what is this girls z-score?
z score formula is:
z = (x-μ)/σ, where
x is the raw score = 44.5 cm
μ is the population mean = 47.18cm
σ is the population standard deviation = 1.40cm
z = 44.5 - 47.18/1.40
z = -1.91429
What does the z score tell us?
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. Using the WHO data in a normal model, what percentage of the girls has a head circumference that is smaller than the girl with Down's Syndrome?
z score = -1.91429
Probability value from Z-Table:
P(z =-1.91429) = P(x<44.5) = 0.027792
Converting to percentage = 0.027792 × 100
= 2.7792%

A triangle has sides of lengths 3.2 cm, 4.8 cm and 3.6 cm. Find the ratio of the lengths of the sides to one another
Answer:3/2
Step-by-step explanation:
i just had this on a test a triangle always equals this
The ratio of the lengths of the sides to one another is 0.8:1.2:0.9.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, a triangle has sides of lengths 3.2 cm, 4.8 cm and 3.6 cm.
The ratio of the lengths is 3.2:4.8:3.6
= 1.6:2.4:1.8
= 0.8:1.2:0.9
Therefore, the ratio of the lengths of the sides to one another is 0.8:1.2:0.9.

How may solutions does -3(x-2)=6-3x have
Answer:
Every real number is a solution.
Step-by-step explanation:
−3 (x − 2) = 6 − 3x
