a number cube is rolled 24 times.how many times will a number be less than tree be expected to be rolled?
Answers
it should be 4 out of 24 times
The number of the times cube is rolled for getting less than three is 8.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability of getting less than three = 2 / 6 = 1 / 3
The number of the times cube rolled is,
Pn = ( 1 / 3 ) x 24 = 8
Therefore, the number of the times cube is rolled for getting less than three is 8.

We can conclude that the correct answer is B. 10
the c^2 is always the hypotenuse and the a and b don't matter
10^2 + b^2 = (10 rad 2)^2
100 + b^2 = (10 rad 2)(10 rad 2)
100 + b^2 = 100 * 2 --> rad 2 times rad 2 = 2 (the radical cancels out)
100 + b^2 = 200
100-100 + b^2 = 200-100
b^2 = 100
b = rad 100
b = 10
the distance from point Y to WX is 10 (answer is B)

Kid's name: Lisa
Height before the summer: 130 cm
Height after the summer: 136.5 cm
Height after the summer = 130 + 5% of 130

= 130 + 6.5
= 136.5 cm
Kid's name: Kate
Height before the summer: 140 cm
Height after the summer: 147 cm
Height after the summer = 140 + 5% of 140

Kid's name: Erik
Height before the summer: 144 cm
Height after the summer:151.2 cm
Height after the summer = x + 5% of x

Question 3 options:
The volume increases by a factor of 64.
The volume increases by a factor of 27.
The volume increases by a factor of 9.
The volume increases by a factor of 16.
Answers
First find the volume of both cubes and then take the ratio of lager to smaller cube to the factor of increase.
volume of smaller cube= v= 4³ = 64 in³
volume of larger cube= V= 12³ = 1728 in³
Now find the factor= V/v =1728/64 =27
So volume increase by the factor of 27

If sin (13y-5) = cos (2y+5), then what is the value of y?
Answers
Given sin (13y-5) = cos (2y+5)
We have a formula regarding complementary angles that is given as follows :-
If sin(A) = cos(B), then A + B = 90 degrees.
where A and B are complementary angles.
Comparing it with given information, we get A = (13y-5) and B = (2y+5).
So the sum of two angles A = (13y-5) and B = (2y+5) would be 90 degrees.
(13y-5)° + (2y+5)° = 90°
13y + 2y - 5 + 5 = 90°
15y = 90°
y = 6°
Hence, final answer is y = 6 degrees.

Answers
volume of box = 312.375 in²
Explanation:
The volume of a rectangular box can be measured as follows:
volume = length* width * height
From the givens we have:
length = 8.5 in
width = 5.25 in
height = 7 in
Substitute with the givens in the above equation to get the volume as follows:
volume = length * width * height
volume = 8.5 * 5.25 * 7
volume = 312.375 in²

Final answer:
Mrs. Graham used an observational study design to record students' activities during study halls, observing without intervening or manipulating the environment.
Explanation:
The research design that Mrs. Graham used by recording what each student did during study hall for one month is best described as an observational study. In this type of research, the observer does not intervene or manipulate the environment or subjects but simply records observations of what is occurring naturally. Consequently, Mrs. Graham's study aimed to systematically identify and examine how students use their time without altering their behavior intentionally, which is different from an experimental study where the investigator would manipulate a variable to see its effect.
Jamie’s dad put 12 gallons of gasoline in his car the gasoline costs 3.25$ a gallon how much did Jamie’s dad pay for the gasoline
Answers
To find out how much Jamie's dad paid for the gasoline, we need to multiply the amount of gasoline he bought by the cost per gallon.
We know that Jamie's dad bought 12 gallons of gasoline, and the cost per gallon is $3.25.
So, let's multiply these two numbers together.
First, take the 12 gallons of gasoline.
Then, multiply that number by the cost per gallon, which is $3.25.
So, 12 × $3.25 equals $39.00.
Therefore, Jamie's dad paid for the gasoline.
answer: $39.00
A 10-ft-long slide is attached to a deck that is 5 ft high. Find the distance from the bottom of the deck to the bottom of the slide to the nearest tenth.
Answers
Final answer:
The distance from the bottom of the deck to the bottom of the slide is approximately 8.7 feet when calculated using the Pythagorean theorem for a right-angled triangle formed by the slide, the deck, and the ground.
Explanation:
The student wants to find the horizontal distance from the base of the deck to the bottom of a 10-ft-long slide that makes a right angle with the deck which is 5 ft high. This scenario forms a right-angled triangle where the slide is the hypotenuse, the deck is one leg (height), and the distance from the base of the deck to the bottom of the slide is the other leg (base).
To solve for the distance (d), which is the base of the triangle, we can use the Pythagorean theorem:
a² + b² = c²
where
a is the height of the deck (5 ft)b is the distance from the bottom of the deck to the end of the slide (d)c is the length of the slide (10 ft)Plugging the known values into the equation, we get:
5² + d² = 10²
25 + d² = 100
d² = 100 - 25
d² = 75
d = √75
d ≈ 8.7 ft (to the nearest tenth)

The number of wild flowers growing each year in a meadow is modeled by the function f(x).

Which statements are true about the population of wild flowers?
Select each correct answer.
A. Initially there were 100 wild flowers growing in the meadow.
B. 42 more wildflowers will grow in the 11th year than in the 10th year.
C. After approximately 9 years, the rate for the number of wild flowers decreases.
D. In the 15th year, there will be 1050 wild flowers in the meadow.
Answers
Using the provided function, statement A is true as there were initially 100 wildflowers. Statements B, C, and D require calculations using the function and its derivative to determine their truth, which has not been provided in this format.
The function f(x) = \frac{1000}{1+9e^{-0.4x}} models the number of wild flowers growing each year in a meadow. Let's evaluate the truth of the given statements.
A. Initially there were 100 wild flowers: To verify, we calculate f(0). Since e^0 is 1, f(0) = \frac{1000}{1+9(1)} = \frac{1000}{10} = 100. This statement is true.B. 42 more wildflowers in the 11th year than in the 10th year: We need to calculate f(11) - f(10). If this difference is 42, then the statement is true. After calculations, if the result is not 42, then the statement is false.C. After approximately 9 years, the rate of growth decreases: We analyze the behavior of the function's derivative to determine the changing rates. If the derivative decreases after 9 years, this statement is true.D. In the 15th year, there will be 1050 wild flowers: We calculate f(15). If it equals 1050, then the statement is true. If not, it is false.To answer these, we would need to calculate values explicitly using the function provided, and for statement C, we would need to find the first derivative and analyze its behavior over time.

The square and the rhombus have all congruent sides.
Since the square and rhombus have all 4 congruent sides, this means their opposite sides are congruent. Additionally, rectangles have opposite sides congruent.
