The probability that the object is green or a cube will be 9/14. Thus, the correct option is D.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
A jar contains 2 blue cubes, 5 blue spheres, 2 green cubes, and 5 green spheres.
The total event is calculated as,
Total = 2 + 5 + 2 + 5
Total = 14
The probability that the object is green or a cube is calculated as,
P = 7 / 14 + 4 / 14 - 2 / 14
P = 1/2 + 2/7 - 1/7
P = 9/14
Thus, the correct option is D.

Priya makes bracelets for her online store. Her monthly business expenses are $520. She sells an average of 80 bracelets per
month. Based on the inequality below, if she wants to profit at least $1,240, how much should she charge, b, per bracelet?
80b - $520 > $1,240
A. Priya needs to charge at most $19 per bracelet.
B. Priya needs to charge at least $22 per bracelet.
C. Priya needs to charge at most $22 per bracelet
D. Priya needs to charge at most $29 per bracelet.
Answer:
B
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = 80 x b
total cost = 520
the profit has to be at least $1240
80 x 22 = 1760
1760 - 520 = 1240
b is correct

In circle H with m ∠ G H J = 90 m∠GHJ=90 and G H = 20 GH=20 units, find the length of arc GJ. Round to the nearest hundredth.
Answer:
180
Step-by-step explanation:
length of arc GJ ≈ 31.42 units.
What is the arc of a circle?A circle's arc is a bent portion of the circle's circumference. Its perimeter is determined by its two ends and the area of the circle that lies in between them. An arc's length or the angle it makes with the circle's center can be used to measure it.
The formula L = θr states that the length of an arc is inversely proportional to the radius of the circle and the angle it subtends. L is the length of the arc, r is the radius of the circle and θ is the angle the arc subtends in radians.
To find the length of arc GJ, we first need to find the circumference of the circle.
The circumference of a circle is given by the formula:
C = 2πr
where C is the circumference, π is a constant approximately equal to 3.14, and r is the radius of the circle.
Since GH = 20 units and HJ is the radius of the circle, we have:
HJ = GH = 20 units
So the radius of the circle is 20 units.
The formula for the length of the arc is 2πr(θ/360)
Since the angle is given 90, the length of the arc:
2*π*20(90/360)
=10 π
Therefore, the length of arc GJ is 10π or 31.42 units.

3) Using your graphing calculator, create a graph of the function f(x) = x2 + 4x + 3 What is the vertex? What are the roots? What is the equation of the axis of symmetry?
Answer:
Step-by-step explanation:
Input the function f(x) = x^2 + 4x + 3 and graph it (using the calculator) for the interval [-5, 5]. The roots are the x values at which this graph crosses the x axis and are {-3, -1). The axis of symmetry is the vertical line through x = -2.
.Find the point of intersection of the pair of lines. x + 5y = 8, -x + 2y = -1
Answer:
the point of interception is where the graphs meets
in this case we will solve using substition method
x + 5y = 8 .... 1
-x + 2y = -1 .....2
solve for the equation
x = 8 - 5y ...... 3
solve the equation in equation 2
-x + 2y = -1
-(8-5y ) + 2y = -1
-8 +5y + 2y = -1
7y = -1 + 8
7y = 7
divided by 7 on both sides
y = 1
solve the value of y in equation 3
x = 8 - 5y
x = 8 - 5(1)
x = 8 -5
x = 3
the point of interception (3 ; 1)

Rebecca asked the people in her homeroom class what their favorite type of pizza was. If 18
out of 25 people said pepperoni, how many people would you expect to choose pepperoni
out of 350 people?
Answer:
x = people who chose pepperoni = 252
Step-by-step explanation:
Number of people : people who chose pepperoni = 25 : 18
how many people would you expect to choose pepperoni
out of 350 people?
Let x = people who chose pepperoni
Number of people : people who chose pepperoni = 350 : x
Equate both ratios
25 : 18 = 350 : x
25/18 = 350/x
Cross product
25*x = 18*350
25x = 6,300
x = 6,300/25
x = 252
x = people who chose pepperoni = 252

A researcher spoke to 20 people running a marathon in which 1,400 people participated. Of those 20 people, 5 competed only in professional sporting events, 12 competed in only amateur sporting events, and the rest competed in both. What was the population size for this study?
A. 5
B. 12
C. 20
D. 1,400
Answer:
Step-by-step explanation:
The population size is everybody running the race. It does not include people watching the race and it is not confined to just the 20 people the researcher talked to.
If it doesn't limit itself to the 20 people, then the 5 and 12 and 3 people are also too limiting.
Since there are no restrictions on the strings, we can think of this problem as drawing 5 random digits in sequence. There is a 9/10 chance each time we draw to NOT get a 4. Every time we draw, we multiply by 9/10 again until we've draw 5 digits. Thus, the answer is (9/10)^5 :)
Answer:
[tex]Pr = 0.59049[/tex]
Step-by-step explanation:
See Comment for Complete Question
Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).
However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)
The probability of selecting a number other than 4 in each of the digit is:
[tex]1st \to \frac{9}{10}[/tex]
[tex]2nd \to \frac{9}{10}[/tex]
[tex]3rd \to \frac{9}{10}[/tex]
[tex]4th \to \frac{9}{10}[/tex]
[tex]5th \to \frac{9}{10}[/tex]
So, the required probability is:
[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]
[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]
[tex]Pr = \frac{9^5}{10^5}[/tex]
[tex]Pr = \frac{59049}{100000}[/tex]
[tex]Pr = 0.59049[/tex]
Wel and George each have a packet of 20 seeds. They are planting seeds in different rows of a garden. Each row is 10 yards long. Wel plants a seed every 4 feet, starting 4 feet from the end of her row. George plants a seed every 2 yards, starting 2 yards from the end of his row. What is the greatest number of full rows that each person can plant using just their packet of seeds? Enter the answers in the boxes. Wei can plant full rows. George can plant full rows.
Answer:
a) Wel can plant four full roes
b) George can plant five full rows
Step-by-step explanation:
The number of seeds in the packet of seeds Wel and George have, n = 20 seeds each
The length of each row of the garden = 10 yards = 30 feet
The distance between the seeds Wel plants, d = 4 feet
The point at which Wel starts to plant the seeds = 4 feet from the end of the row
The distance between the seeds George plants = 2 yards
The point George starts to plant the seeds = 2 yards from the ends his row
Therefore, we have;
a) The length of each row Wel plants her seeds, l = 10 yd. - 4 ft. = 26 ft.
The number of seeds she plants per row = The whole number part of l/d
l/d = 26 ft./(4 ft./seed) = 6.5 seeds
∴ The number of seeds she plants per row, s = 6 seeds
The number of rows Wels plants her seeds, r = The next whole number of the ratio, n/s =
n/s = 20/6 = 3.[tex]\overline 3[/tex]
∴ The number of rows Wels plants 4 full rows
Therefore;
Using just her packet of seeds, Wels can plant four rows in the garden
b) The length of each row George plants his seed = 10 yd. - 2 yd. = 8 yd.
The number of seeds he plants per row = 8 yd./row/(2 yd./seed) = 4 seeds/row
The number of rows he plants his seeds = 20 seeds/(4 seeds/row) = 5 rows
The number pf rows George plants his seeds = 5 rows
Using just his packet of seeds, George can plant 5 full rows
