The theoretical probability of selecting a consonant at random from a list of letters in the alphabet is 21/26. Wayne opens a book, randomly selects a letter on the page and records the letter. He repeats the experiment 200 times. He finds p(consonant) = 60%. How does the theoretical probability differ from the experimental probability? What are some possible sources for this discrepancy. I will mark brainlest
Answer:
The theoretical probability in this case is calculated by taking the number of consonants in the alphabet and dividing it by total number of letters in the alphabet and the distribution of letters in the written language is different than the distribution of letters in the alphabet.

The volume would be...
The surface area would be....
Hi, sorry for a late response, but here are the answers if they are still helpful?
The volume would be about 4,188.79
(if rounded and if not the answer is below and so is the work.)
Volume = 4
—— πr3
3
= 4
—— ✖️ π ✖️ 103
3
= 4188.7902047864 centimeters^3
The surface area would be about 1,256.64
(if rounded and if not the answer is below and so is the work.)
Surface Area = 4πr2
= 4 × π × 102
= 400π
= 1256.6370614359 centimeters^2
When a spaceship full of scientists landed on Planet Q, they found that 3/8 of the 160 aliens had 3 eyes. The rest of the aliens had 5 eyes. How many eyes total do the 160 aliens have?
Answer:
680 eyes.
Step-by-step explanation:
160 · 3/8 = 60
60 aliens have 3 eyes. That means the other 100 aliens have 5 eyes.
60 · 3 = 180
100 · 5 = 500
500 + 180 = 680
Therefore, the 160 aliens have a total of 680 eyes.

Answer: C
Step-by-step explanation:
Diego has 75% of $10. Noah has 25% of $30. Diego thinks he has more money than Noah, but Noah thinks they have an equal amount of money. Who is right? Explain your reasoning.
Answer:
.75 x 10 = $7.5
.25 x 30 = $7.5
They have the same amount so Noah is right
Step-by-step explanation:
Answer:
They have the same amount so Noah is right
Step-by-step explanation:
0.75 x 10 = $7.5

0.25 x 30 = $7.5
A certain shampoo is available in two sizes. A 14.2-ounce bottle costs $3.98. A 33.9-ounce bottle costs $9.98.
Find the unit price for each size. Then state which size is the better buy based on the unit price.
Round your answers to the nearest cent.
Answer:
28 cents, 29 cents, The 14 oz bottle is the better buy.
Step-by-step explanation:
For part 1: Divide 3.98 ÷ 14.2. That equals 28 cents.
For part 2: Divide 9.98 ÷ 33.9. That equals 29 cents, one more than the other shampoo.
That means that shampoo 1 is the better buy

Find x please I will give brainlest.
Answer:
x=28
Step-by-step explanation:
6(x+2)=180 Step 1: Write equation
6x+12=180 step 2: Expand the equation
6x=168 Step 3: Do 180-12 first
x=28 Step 4: Divide by 6 answer you got in Step 3
Step 5: replace 28 with x to see if it's correct 6(28+2)= 180

Use the function f(x) to answer the questions. f(x) = −16x2 + 60x + 16 Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Step-by-step explanation:
x intercept y=0
0 = 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
Answer:
x intercept y=0
0
= 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
Step-by-step explanation:
0 = 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.
Answer:
The toy reaches the ground in 10 sec
Step-by-step explanation:
When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,
Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,
the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.
The quadratic formula is as follows:
-b ± √discriminant
t = -------------------------------
2a
which here is:
-50 ± 50.39
t = ------------------------ Since t represents time, only the positive result
-9.8 is relevant here; it is 10.24 sec,
which rounds off to 10 sec
The toy reaches the ground in 10 sec

What equals 2?
What equals 3?
What equals 4?
What equals 5?
Answer:
Step-by-step explanation:
(4x4)÷(4+4) = 2
(4x4)÷ (4 +4) - 4= 4
(4+4)+(4÷ 4)- 4= 5
(4+4)- (4÷4) - 4= 3
