Answer:
25% chance
Step-by-step explanation:
There are 3 prime numbers on a 6-sided die so that means there is a 1/2 chance you roll a prime number. In order to calculate the probability of 2 or more events you multiply their probability which would be
1/2 * 1/2 = 1/4
So the chance of rolling a prime number on both rolls is a 1/4 chance or a 25% chance
The probability that she will roll a prime number both times is 0.25.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Martha rolls a 6 sided number cube two times.
And the prime numbers in the cubes are {2, 3, 5}.
The probability that she will roll a prime number both times,
= 3/6 x 3/6
= 1/2 x 1/2
= 1/4
= 0.25
Therefore, 0.25 is the probability.

A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?
P=2500(0.25)^t
P=2500+0.25t
P=2500(0.75)^t
P=2500(1+0.25)^t
Answer:
P=2500(1+0.25)
Step-by-step explanation:
Given data
Initial population= 2500
Rate= 25%
The exponential increase is described using the expression
P=A(1+r)^t
Hence the correct representation is
P=2500(1+0.25)
A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is 30 feet, the height of the roof is 12 feet, and the height of the entire silo is 60 feet?
147,026.5 ft
135,716.8 ft
180,955.7 ft
169,646.0 ft
Answer:
The volume of the silo is approximately 147,026.6 ft.³.
The most correct option is 147,026.5 ft.³
Step-by-step explanation:
The given dimensions of the silo are;
The shape of the silo = Composite figure of tower and roof
The shape of the tower = Cylindrical
The shape of the roof = Cone
The radius of the base of the silo, 'r' = 30 feet
The height of the cone roof of the silo, h₁ = 12 feet
The height of the entire silo = 60 feet
For the cone roof, we have;
The volume of a cone, V = 1/3 × Base area × Height
The volume of the cone roof, V₁ = 1/3×π·r² × h₁
∴ V₁ = 1/3 × π × (30 ft.)² × 12 ft. ≈ 11,309.7336 ft.³
For the cylindrical tower, we have;
The height of the entire silo = The height of the tower + The height of the roof
∴ The height of the tower = The height of the entire silo - The height of the roof
The height of the tower, h₂ = 60 ft. - 12 ft. = 48 ft.
The volume of a cylinder = Area of base × Height
The volume of the cylindrical tower, V₂ = π·r² × h₂
∴ V₂ = π × (30 ft.)² × 48 ft. ≈ 135,716.803 ft.³
The volume of the cylindrical tower, V₂ ≈ 135,716.803 ft.³
The volume of the (entire) silo, Vₙ = V₁ + V₂
∴ Vₙ = 11,309.7336 ft.³ + 135,716.803 ft.³ = 147,026.573 ft.³
The volume of the (entire) silo, Vₙ ≈ 147,026.6 ft.³.
Answer:
147,026.5 ft.³

Heather puts together 25 of a puzzle on Saturday and 310 on Sunday. Nicole has the same puzzle, and she puts together 45 of her puzzle. How much more of the puzzle does Nicole put together than Heather? A. 110 B. 310 C. 15 D. 45
Answer:
1/10
Step-by-step explanation:
Here is the correct answer
Heather puts together 2/5 of a puzzle on Saturday and 3/10 on Sunday. Nicole has the same puzzle, and she puts together 4/5 of her puzzle.How much more of the puzzle does Nicole put together than Heather? A. 1/10 b. 3/10 c. 1/5 d 4/5
total puzzle heather put together =
[tex]\frac{2}{5} + \frac{3}{10}[/tex]
[tex]\frac{4 + 3}{10}[/tex] = 7/10
the next step is to subtract 7/10 from the fraction Nicole put together
[tex]\frac{4}{5} - \frac{7}{10}[/tex]
[tex]\frac{8-7}{10}[/tex] = 1/10

7. After a discount of 30%, you pay $49.00 for a video game. What was the original price of the game?
Answer:
$70.00
Step-by-step explanation:
Percentage of original price paid
= 100% -30%
= 70%
70% of original price ----- $49.00
1% of original price ----- $49.00 ÷70= $0.70
100% of original price ----- $0.70 ×100= $70.00

Los hombres adultos tienen alturas con una media de 69.0 pulgadas y una desviación estándar de 2.8 pulgadas. Encuentre la puntuación z de un hombre de 70.3 pulgadas de alto. (Redondee la respuesta con 4 decimales)
Answer:
0.4643
Step-by-step explanation:
z = (x-μ) / σ, donde
x es la puntuación bruta = 70.3 pulgadas
μ es la media de la población = 69 pulgadas
σ es la desviación estándar de la población = 2.8 pulgadas
z = (70.3 - 69) /2.8
z = 0.46429
Aproximadamente a 4 lugares decimales = 0.4643
