Find the probability that a student earns a
grade of B.
p = [?]
Enter a decimal rounded to the nearest hundredth.
Answer:
0.29
Step-by-step explanation:
Total grade frequency = (5 + 10 + 15 + 3 + 2) = 35
Frequency of grade B = 10
Probability = required outcome / Total possible outcomes
Required outcome = frequency of grade B = 10
Total possible outcomes = total grade frequency = 35
P(B) = 10 / 35
P(B) = 0.2857
P(B) = 0.29

Find the value of x
Please help out!!
Answer:
x = 12
Step-by-step explanation:
(2x + 4) and (12x + 8) are same- side interior angles and sum to 180° , then
2x + 4 + 12x + 8 = 180
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
Find the value of x
Answer:

n ΔHIJ, the measure of ∠J=90°, HJ = 21, JI = 20, and IH = 29. What ratio represents the cosine of ∠H?
Answer: The ratio represents the cosine of ∠H = [tex]\frac{21}{29}[/tex]
Step-by-step explanation:
Given, In right triangle ΔHIJ, the measure of ∠J=90°, HJ = 21, JI = 20, and IH = 29.
To find: The ratio represents the cosine of ∠H.
According to trigonometry, the cosine of x = [tex]\frac{\text{side adjacent to x}}{\text{Hypotenuse}}[/tex]
So cosine of [tex]\angle H=\frac{HI}{HJ}[/tex]
Cosine of [tex]\angle H=\frac{21}{29}[/tex]
hence, the ratio represents the cosine of ∠H = [tex]\frac{21}{29}[/tex]

Triangle XY Z has vertices X = (5, -1), Y = (1, 4), and Z=
(-8,0). Triangle X'Y'Z' is formed when triangle XYZ is
reflected over the y-axis. What are the coordinates of
triangle X'Y'Z'?
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
X (5, - 1 ) → X' (- 5, - 1 )
Y (1, 4 ) → Y' (- 1, 4 )
Z (- 8, 0 ) → Z' (8, 0 )

Answer:
7.76
Step-by-step explanation:
tan 29° = XY/14
XY = tan 29° (14)
= 7.76
Answer:
XY=7.76
Step-by-step explanation:
Tan25° says opp÷adj
so it's Tan29°=XY÷14
then multiply both sides by 14 to make CY the subject of the formula...
14×Tan29°=XY
therefore=XY=7.76

Given:
The figure of a rhombus QRST.
To find:
A. The value of x.
B. The measure of angle RQP.
Solution:
A. We need to find the value of x.
We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.
[tex]m\angle RPS=90^\circ[/tex] [Right angle]
[tex](5x+15)^\circ=90^\circ[/tex]
[tex](5x+15)=90[/tex]
[tex]5x=90-15[/tex]
[tex]5x=75[/tex]
Divide both sides by 5.
[tex]x=\dfrac{75}{5}[/tex]
[tex]x=15[/tex]
Therefore, the value of x is 15.
B. We need to find the measure of angle RQP.
From the given figure, it is clear that
[tex]m\angle RQP=(2x+3)^\circ[/tex]
Putting [tex]x=15[/tex], we get
[tex]m\angle RQP=(2(15)+3)^\circ[/tex]
[tex]m\angle RQP=(30+3)^\circ[/tex]
[tex]m\angle RQP=33^\circ[/tex]
Therefore, the measure of angle RQP is 33 degrees.
How do you write 0.0006363 in scientific notation?
Answer:
Step-by-step explanation:
Proper scientific notation means that there is only 1 number to the left of a decimal and everything else to the right of it. Also, because the number is initially less than 1, the exponent will be a negative one. We have to move the decimal 4 places to the right in order to get the 6 to the left of it, so in correct scientific notation format, we have
[tex]6.363*10^{-4[/tex]

How are formulas for the volume of a cylinder, pyramid, and cone derived?
Answer:
Calculus-based analytic geometry makes the cylinder, pyramid, and cone from "solids of revolution". From there, they can measure the length or radius of the base, and then the height. This is true even if the solid of revolution is along the X axis intead of the Y axis. Then someone "figured out" the formula, just like they did with a cube, and proved it.

Mikes fishing lure Is 21 feet below the surface of the water how many feet does he need to reel in his lyre to reach the surface of the water?
Answer:
21 feets
Step-by-step explanation:
Since the lure is 21 feets beneath the water surface,
The the elevation of the lure is - 21 feets
If the surface of water = x
Then current distance of lure equals :
x - 21
To obtain the nunber of feets to reach the water surface ;
x - 21 = 0
x = 21 feets

A patio is shaped like the figure shown below with the length of each square
equal to 1 meter. Anthony wants his patio to look awesome therefore he will
cover it with tiles. The tiles cost $4 per meter square. How much will it cost to
cover the patio with tiles? (Hint: Find the area of the composite figure then
multiply it by 3)
Answer:
[tex]\$ 80[/tex]
Step-by-step explanation:
Since we know the price per square meter, we can find area of the figure and multiply it by the price per square meter.
The area of the composite figure consists of a trapezoid and a rectangle.
Area of trapezoid: [tex]\frac{(8+4)}{2}\cdot 2=6\cdot 2 = 12\:\mathrm{m^2}[/tex]
Area of rectangle: [tex]4\cdot 2=8\:\mathrm{m^2}[/tex]
Therefore, the area of the composite figure is equal to [tex]12+8=\boxed{20\:\mathrm{m^2}}[/tex]. Since the problem states that it will cost Anthony $4 per square meter, the total cost to tile the entire figure will be [tex]20\cdot 4=\boxed{\$80}[/tex]
during a sale, a shopkeeper reduced the prices of all his goods by 15 %. Calculate the normal selling price of microwave which was sold for Rs 3825 in the sale.
Answer:
Normal selling price is Rs 4500
Explanation:
1) Selling price = original price × (100-d) / 100
d = reduced price percentage
2) Rearrange the formula
original price = (selling price × 100) / (100 - d)
S.p = 3825
d= 15%
let original price = x
Therefore
x = (s.p×100) / (100-d)
x = (3825×100) ÷ (100-15)
x = 382500/85
x = 4500
consider the original price x
offer15% = 15x/100
Saling price = x - 15x/100
3825 = 85x/100
x = (3825×100)÷ 85 = 4500 rs
Answer the normal selling price of microwave which was sold for Rs 3825 in the sale is 4500 rs

I really need help!!!!!!!
Answer:
x=10 3x= 30
Step-by-step explanation:
3x = 30 since the angles are vertical angles
3x/3 = 30/3
x = 10
Answer:
B
Step-by-step explanation:
Set up an equation:
30 = 3x
Divide both sides by 3:
10 = x
x = 10 degrees
Plug the value of x into the angle:
3 × 10
30 degrees

What is the length of the missing leg?
x^2=6x+1
rewrite the equation by completing the square your equation should look like (x+a)^2=b or (x-c)^2=d
What are the solutions to the equation?
Answer:
x=3+√10 or x=3−√10
Let's solve your equation step-by-step.
x2=6x+1
Step 1: Subtract 6x+1 from both sides.
x2−(6x+1)=6x+1−(6x+1)
x2−6x−1=0
For this equation: a=1, b=-6, c=-1
1x2+−6x+−1=0
Step 2: Use quadratic formula with a=1, b=-6, c=-1.
x= −b±√b2−4ac

Step-by-step explanation:
This season, the probability that the Yankees will win a game is 0.6 and the probability that the Yankees will score 5 or more runs in a game is 0.57. The probability that the Yankees lose and score fewer than 5 runs is 0.34. What is the probability that the Yankees would score fewer than 5 runs when they win the game? Round your answer to the nearest thousandth.
The probability that the Yankees would score fewer than 5 runs when they win the game is 0.204 if the probability that the Yankees will win a game is 0.6
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The probability that the Yankees will win a game P(win) = 0.6
The probability that the Yankees will score 5 or more runs in a game is:
P(s>5) = 0.57
The probability that the Yankees lose and score fewer than 5 runs is:
P(s<5) = 0.34
To find the probability that the Yankees would score fewer than 5 runs when they win the game:
This is the case of probabilities of one event and another event together we will multiply the respective probabilities of the event:
= P(win)×P(s<5)
= 0.6×0.34
= 0.204
Thus, the probability that the Yankees would score fewer than 5 runs when they win the game is 0.204 if the probability that the Yankees will win a game is 0.6
