Answer:
15
Step-by-step explanation:
The cards have 5 possible outcomes and the spinner has 3 possible outcomes. To find the sample size, you need to calculate the number of possibilities when drawing 1 card and landing on 1 side of the spinner. You can do this by multiplying the possible outcomes together.
5×3 = 15
Therefore, the sample size is 15.
Answer:
Option 1: 15
Step-by-step explanation:
Ricky is playing a game using 5 cards and a spinner
Card 1 , Card 2 , Card 3 , Card 4 , Card 5
and
㉦ Green, Red, Blue
Ricky picks a card and spins the spinner
The sample size outcome is:
{(1, G) (1, R) (1, B) (2, G) (2, R) (2, B) (3, G) (3, R) (3, B) (4, G) (4, R) (4, B) (5, G) (5, R) (5, B)}

the function f(x)=x^2 is transformed to the function g(x)=2(x-2)^2 +1
I already did a just need help sketching the original graph please review the picture I made It easy
Answer:
f(x) → f(x - b) means shift the function b units to right
Therefore x² → (x - 2)² means the function is moved 2 units to the right.
f(x) → a f(x) means a vertical stretch
Therefore (x - 2)² → 2(x - 2)² means the function stretched vertically by a scale factor of 2.
f(x) → f(x) + b means shift the function b units up
Therefore 2(x - 2)² + 1 means the function is moved 1 unit up.
Attached diagram:
f(x) is shown in black, g(x) is shown in red.
Points to help plot graph f(x):

To get to Checkpoint C, Helena needs to run north 6 units, crawl through a 4-unit-long tube to the east, hopscotch south 3 units, jump 1 unit to the east, and run south 3 units.
1. Since she began at Checkpoint B, what are the coordinates for Checkpoint C?
2. What would be an easier way to get from Checkpoint B to Checkpoint C?
3. How might you be able to figure this out just by reading the description of the translations? (Hint: It may help you to plot these points on a graph or draw a picture.)
Helena's motions, including the 6 units north, 4 and 1, east, 3 and 3 south gives;
(5, 0)5 units to the southAdding the motions based on their directionsHow can the position of Helena be found?1. Let the coordinates of checkpoint B be (0, 0), using vectors, we have;
[tex]6 \times j \: + 4 \times i - 3 \times j \: + i - 3 \times j = 0 \times j \: + 5 \times i[/tex]
The coordinates of checkpoint C is therefore; (5, 0)
2. The easier way to get to checkpoint C from point B is to go south 5 units.
3. How it is possible to figure out the shortest route is by taking the northwards and eastwards motions as positive numbers, and the motions to the south as negative.
The motions to the north can only be added to the motions to the south (motions in the same straight line) and the motions towards east are to be added to themselves.

27. The perimeter of a rectangle is 46 inches. If the width of the rectangle is 11 inches, what is
the length?
A. 12 in
B. 23 in
C. 35 in
D. 24 in
Answer:
12
Step-by-step explanation:
perimeter is (a+b) x 2 = 46
a is width and b is length
a=11
(11+b) x 2 = 46
22 + 2b = 46
2b = 24
b = 12 ( length )
Solution:
We know that:
Width of rectangle = 11 inchesPerimeter of rectangle = L + B + L + B = 2L + 2BSubstitute the width in the expression:
2L + 2B = Perimeter2L + 2(11) = 46 inSimplify the LHS:
2L + 22 = 46 inSubtract 22 both sides:
2L = 46 - 222L = 24Divide 2 both sides:
2L/2 = 24/2L = 24/2 = 12 inif a and b are integers, what conditions would make a×b >0?
Answer:
If a and b are either both positive integers or both negative integers
Step-by-step explanation:
If a and b are both positive integers (a>0 and b>0), then the product will obviously be a positive number. Additionally, if both terms are negative (a<0 and b<0), the product of two negative integers is positive and will satisfy the condition.
Integers are numbers without decimal points.
The conditions that would make [tex]\mathbf{a \times b > 0}[/tex] are: a, b > 0 or a, b < 0
From the question, we have:
[tex]\mathbf{a \times b > 0}[/tex]
Divide both sides by a
[tex]\mathbf{b > 0}[/tex]
Divide both sides by b
[tex]\mathbf{a > 0}[/tex]
The above means that, for [tex]\mathbf{a \times b > 0}[/tex] to be true, then [tex]\mathbf{a > 0}[/tex] and [tex]\mathbf{b > 0}[/tex]
Another possible condition is that:
[tex]\mathbf{a \times b > 0}[/tex]
Divide both sides by -a
[tex]\mathbf{b<0}[/tex]
Divide both sides by -b
[tex]\mathbf{a<0}[/tex]
The above means that, for [tex]\mathbf{a \times b > 0}[/tex] to be true, then [tex]\mathbf{a<0}[/tex] and [tex]\mathbf{b<0}[/tex]
Hence, the condition that would make [tex]\mathbf{a \times b > 0}[/tex] true is that: a and b have the same sign

Quincy ordered a meal at a restaurant for $9.85. After a tax
of 3.3% was added, he added a 22% tip.
How much did Quincy pay?
Answer:
$12.42
Step-by-step explanation:
so the meal itself was $9.85
9.85*3.3% approximately equals $0.33
9.85+0.33=10.18
10.18*22% approximately equals $2.24
10.18+2.24=12.42
Therefore the answer is $12.42

Step-by-step explanation:
The value of the correlation coefficient is -0.993, The correct option is A.
What is the Correlation Coefficient?The coefficient used to determine how strong is the relation between the two variables in the data set is the Correlation Coefficient.
The correlation coefficient is determined by using the following formula
[tex]\rm r = \dfrac{ n(\sum xy) - \sum x\sum y}{\sqrt {n\sum x^2 - (\sum x)^2 }\sqrt{n\sum y^2 - (\sum y)^2}}[/tex]
The values of the required data will be calculated from the data given
n = 4 rows
∑x = 42
∑y = 44.37
∑xy = 461.3
∑x^2 = 446
∑y^2 = 494
Putting the values in the equation of correlation coefficient:
r = -0.993
Therefore, the value of the correlation coefficient is -0.993, The correct option is A.

Step-by-step explanation:
Barbara is buying 4 binders, and each binder costs the same amount. She uses a coupon that gives her $3 off for the total purchase price of the binders. Barb pays a total of $11 when the value of the coupon is subtracted. Which equation shows how to find p, the original price of each binder?
Answer:
Equation is 4 p-3=11
Step-by-step explanation:
Barbara is buying 4 binders each cost same amount.
Let the cost of 1 binder is '$p'.
So, cost of 4 binders = $4 p.
Now, a coupon that gives her $3 off.
So, Barb needs to pay 4 p-3 dollars.
Barb pays a total of $11 when the value of the coupon is subtracted.
So, we can set up equation as
4 p-3=11
