Answer:
D
Step-by-step explanation:
Probability that the die will show an even number
in one rolling is 3/6=0,5 = p
We have formula for repeating rolling
n!/(r!(n-r)!) p^r (1-p)^(n-r)
n = how many times we repeat rolling = 6
r = how many times we want something to happen
(show an even number exactly two times) = 2
15 *(0,5)^2 *(0,5)^4 = 0,234375
A trapezium has an area of 150cm^2.
The lengths of its parallel sides are 4.8 cm and 5.2 cm.
What is the perpendicular height of the trapezium?
Step-by-step explanation:
Area of Trapezium=1/2 (a+b)h =>
1/2(4.8+5.2)h=15 => h=15/5 =3 cm Ans
Area of trapezium = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides).
A = 1/2 h(a+b)
150 = 1/2 h(4.8+5.2)
150 = 5h
h = 30 cm
Answer - perpendicular height of the trapezium is 30 Cm

A scientist is interested in whether stretching before running 5 kilometers will improve a runner's time. The
scientist decides that an experimental study is the best method to use to answer the question. One group of
runners will run a 5-kilometer race without stretching, and a second group of runners will follow a specific
stretching routine before running the race. The finishing times will be recorded, along with the group type for
each runner
The group that raced without stretching has a mean finish time of 23.5 minutes and a standard deviation of 2.6
minutes. Write a sentence or two that summarizes any conclusions that can be made about the statistical
question, "Does stretching before running a race improve a runner's time?"

Yes

Properties of a parallelogram:
has four right angles- no opposite sides are congruent - yes diagonals are perpendicular to each other- no diagonals bisect each other - yes diagonals are congruent to each other - no opposite sides are parallel - yes diagonals bisect the opposite angles - no opposite angles are congruent - yesFind the value of tanθ, if cosθ = 4/5 ; 0° ≤ θ< 90°
Answer:
3/4Step-by-step explanation:
Given
cosθ = 4/50° ≤ θ < 90°In the first quadrant both sine and cosine are positive, so as tangent.
tanθ = sinθ / cosθ = [tex]\sqrt{1 - cos^2}[/tex]θ / cosθ = [tex]\sqrt{1 - (4/5)^2}[/tex] / 4/5 = [tex]\sqrt{9/25}[/tex] / 4/5 = 3/5*5/4 = 3/4875 × 36 I'll crown and give five stars if you say the solving steps

A windshield wiper is 18 inches long and its blade is 12 inches long. It sweeps through an angle of 130 degrees. What is the total area wiped by the windshield wiper?
Answer:
[tex]A=65 inches^2[/tex]
Step-by-step explanation:
From the question we are told that:
Length of wiper [tex]x=18[/tex]
Length of blade [tex]y=12[/tex]
Angle[tex]\theta=130\textdegree[/tex]
Generally the equation for Cover Area windshield wiper A_w is mathematically given by
[tex]A_w=x^2*\frac{\theta}{360}[/tex]
[tex]A_w=18^2*\frac{130}{360}[/tex]
[tex]A_w=117 \textdegree[/tex]
Generally the equation for Cover Area windshield blade A_b is mathematically given by
[tex]A_b=y^2*\frac{\theta}{360}[/tex]
[tex]A_b=12^2*\frac{130}{360}[/tex]
[tex]A_b=52 \textdegree[/tex]
Therefore total Area wiped by windshield wiper A
[tex]A=A_w-A_b[/tex]
[tex]A=65 inches^2[/tex]

What is ascending Order?Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right. Ascending order is also sometimes named as increasing order. For example, a set of natural numbers are in ascending order, such as 1 < 2 < 3 < 4 < 5 < 6 < 7 < 8… and so on.
We have,
Tickets for all of the described charity raffles cost $2 per ticket.
Here first the player will be choose from A to J and the player wins $150.
Second, the player will be choose from A to O and the player wins $240.

Max is taking a cab in New York City. The fare is calculated as a base charge of $3.00 plus an additional $2.00 per mile traveled. It is also customary to leave a $2 tip.If Max wants to spend exactly $20, how many miles can he travel?
Answer: 7.5miles
Step-by-step explanation:
Since the fare is calculated as a base charge of $3.00 plus an additional $2.00 per mile traveled and also customary to leave a $2 tip and Max wants to spend exactly $20. This information can be formed into an equation as:
Let the miles that he can travel be m.
3 + (2 × m) + 2 = 20
3 + 2m + 2 = 20
5 + 2m = 20
2m = 20 - 5
2m = 15
m = 15/2
m = 7.5miles
Therefore, Max can travel 7.5miles

One metre of ribbon costs $0.45. If Tabitha buys 225 metres of ribbon, how much will she have to pay? (Please help me! I have to turn it in in maximum 1 hour)
Answer: $101.25
Step-by-step explanation:
Since we are given the information that one metre of ribbon costs $0.45 and that Tabitha buys 225 metres of ribbon, the amount that she will have to pay will be gotten by multiplying the cost of one meter of ribbon by the total meters that she bought. This will be:
= $0.45 × 225
= $101.25
Therefore, the cost is $101.25
