Step-by-step explanation:
1)The probability of choosing a blue garment is 1/2
2)The probability of choosing a shirt is 1/3.
Thomas has 1 blue shirt
Thomas has 1 green shirt
Thomas has 1 blue hat
Thomas has 1 green scarf
Thomas has 1 blue pair of pants
Thomas has 1 green pair of pants
So, number of blue garments = 3
Number of shirts = 2
Total garments =6
What is probability?Probability is the measure of the likelihood of an occurrence.
P(event) = Favorable outcomes / Total outcomes
P(blue garment) = 3/6 =1/2
P(shirt) = 2/6 =1/3
Hence, 1)The probability of choosing a blue garment is 1/2
2)The probability of choosing a shirt is 1/3.

a pitcher contains 17.5 cups of iced tea. you drink 0.75 cup of tea each morning and 1.75 cups of tea each evening. when will you run out of iced tea?
Answer:
7 days
Step-by-step explanation:
Based on the amount of iced tea in the pitcher and the amount drank per day, you will run out of iced tea in 7 days.
The total number of cups drank per day is:
= 0.75 + 1.75
= 2.5 cups
With 2.5 cups being drank per day, the pitcher would last:
= Pitcher quantity / Cups per day
= 17.5/2.5
= 7 days
In conclusion, you will run out after 7 days.

There is a line that includes point (1,2) and has a slope of 10 what is equation in intercept form
Answer:
[tex]y=10x-8[/tex]
Step-by-step explanation:
Given: Point (1,2) lies on the line such that it's slope is 10.
To find: equation of line
Solution:
Let m be the slope of line and b be the y - intercept.
Here, slope is a number that describes the direction and the steepness of the line.
y-intercept is the y-coordinate of the point where the graph of the line intersects the y-axis.
Equation of line is [tex]y=mx+b[/tex]
Put [tex](x,y)=(1,2),m=10[/tex]

A baseball coach purchased a total of 28 helmets and caps. Each helmet cost $21.50, and each cap cost $8.25. If the coach spent a total of $363.50, how many helmets did the coach purchase?
Answer:
5 helmets
31 caps
8.25, 16.50 24.75 33 x 10 = 330
330/2 = 165 = 20 helmets
363.50 - 165 = 198.50
5 x 21.50 = 107.50 (+ 11 x 8.25 = 16.50+24.75 +24.75+24.75 = 49.50+41.25) =£91 + 107.50 = 198.50
20+11 = 31
31 caps
5 helmets
Step-by-step explanation:
There are 10 helmets did the coach purchase.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
A baseball coach purchased a total of 28 helmets and caps.
And, Each helmet cost $21.50, and each cap cost $8.25. and the coach spent a total of $363.50.
Let number of helmets = x
And, Number of caps = y
Here, A baseball coach purchased a total of 28 helmets and caps.
Hence, We get;
⇒ x + y = 28 ..(i)
And, Each helmet cost $21.50, and each cap cost $8.25. and the coach spent a total of $363.50.
Hence, We get;
⇒ 21.50x + 8.25y = 363.50
⇒ 5 (4.30x + 1.65y) = 5 × 72.7
⇒ 4.30x + 1.65y = 72.7 .. (ii)
Multiply by 4.30 in (i) ad subtract from (ii);
⇒ 4.30x + 4.30y - 4.30x - 1.65y = 120.4 - 72.7
⇒ 2.65y = 47.7
⇒ y = 18
And, From (i);
⇒ x + y = 28
⇒ x + 18 = 28
⇒ x = 10
Hence, Number of helmets = 10

Morgan works at a store that sells clothing accessories. The supply function
for baseball caps is p= Q-4, where Pis the price and Q is the quantity of
baseball caps. If Morgan sells the baseball caps for $18 apiece, how many
baseball caps will the store supply?
A. 18 baseball caps
B. 22 baseball caps
C. 26 baseball caps
D. 4 baseball caps
Answer:
The number of supply of base balls is 22
Step-by-step explanation:
Given
P = Q - 4
Price = $18
Required
Number of supply
The relationship between price and quantity is given to be P = Q - 4 where price is represented by P and Q represents the quantity.
To get the quantity supply when price is $18, all you need to do is to substitute 18 for P in the above equation;
Thus, giving:
18 = Q - 4
Make Q the subject of formula
Q = 18 + 4
Q = 22 quantities
Hence, the number of supply of base balls is 22
Answer:
B. 22 baseball cap
Step-by-step explanation:
P=Q-4
Make Q the subject of the formula
P+4=Q
Therefore,
Q=p+4
If Morgan sells the baseball cap for $18
Q=18+4
Q=22
Morgan store will supply 22 baseball caps

What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
parabola, open curve, a conic segment produced via the intersection of a proper circular cone and a plane parallel to an element of the cone.
On a coordinate plane, a line with a negative slope goes through points (0, 1.5) and (2, 1)
So this is a linear function

account for a year, which bank would pay her more in interest, and by how
much?
Answer:
Bank B by 82 cents.
Step-by-step explanation:
Got it correct on the quiz.
Bank B would pay more interest than Bank A by $0.82
What is compound interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Given that, Ariana wants to deposit $1000, she needs to choose between two offers Bank A offers 4% compounded quarterly and Bank B offers 4.1% compounded semiannually.
We need to determine which Bank will offer her more,
The compound interest formula is equal to =
[tex]A = P(1+r/n)^{nt}[/tex]
where,
A is the Final Investment Value
P is the principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
Bank A =
t = 1
P = 1000
r = 0.04
n = 4
[tex]A = 1000(1+0.04/4)^{4}[/tex]
A = $1040.6
Bank B =
t = 1
P = 1000
r = 0.04
n = 2
[tex]A = 1000(1+0.041/2)^{2}[/tex]
A = $1041.42
Hence, the Bank B would pay more interest than Bank A by $0.82

The hourly wages earned by 20 employees are shown in the first box-and-whisker plot below. The person earning $15 per hour quits and is replaced with a person earning $8 per hour. The graph of the resulting salaries is shown in plot 2. A box-and-whisker plot is shown. The number line goes from 7 to 15. The whiskers range from 8 to 15, and the box ranges from 8.8 to 10.2. A line divides the box at 9.5. Plot 1 A box-and-whisker plot is shown. The number line goes from 7 to 15. The whiskers range from 8 to 11, and the box ranges from 8.7 to 10. A line divides the box at 9.6. Plot 2 How does the mean and median change from plot 1 to plot 2? The mean and median remain the same. The mean decreases, and the median remains the same. The mean remains the same, and the median decreases. The mean and median decrease.
Answer:
The mean decreases, and the median remains the same.Step-by-step explanation:
Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.
In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.
Now, the range of the data set decreases from 7 to 3.
On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.
Therefore, the right answer is The mean decreases, and the median remains the same.

The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6. How does the theoretical probability compare with the experimental probability of landing on an even number? Use the drop-down menus to explain your answer. The_______ probability is greater than the_____ probability of landing on an even number. The_______ probability is 72/120 and the_______ probability is 80/120.
Answer:
The theoretical probability is greater than the experimental probability of landing on an even number. The experimental probability is 72/120 and the theoretical probability is 80/120.
Step-by-step explanation:
Experimental probability of landing on an even number: (30+25+17)/120 = 72/120 = 0.6
Even outcomes: 4
Total outcomes: 6
Theoretical probability of landing on an even number: 4/6 = 0.67
After 120 spinners it is expected 4/6*120 = 80 even results
