When you roll two number cubes, what are the odds, in simplest form, in favor of getting two numbers less than 3?
A. 1:8
B. 8:1
C. 1:9
D. 9:1
Answer:
A
Step-by-step explanation:
The successful results are
1 1
2 1
1 2
2 2
So the formula is probability of winning to probability of losing
Probability of winning =
4/36 = 0.1111111
Probability of losing =
32/36 = 0.88888888
So the odds are expressed as 0.111111 / 0.88888 = 1 in 8

An hour before show time, only 266 people are seated for a movie. . According to ticket sales, 93% of the people have yet to arrive. How many tickets were sold for the movie
Answer:
3800 tickets
Step-by-step explanation:
we are given that,
total people seated:266
yet to come:93%
so the percentage of people who have arrived is 100%-93%=7%
and one ticket for each people
therefore,
[tex] \displaystyle \begin{array}{ccc} \displaystyle \rm7\% \quad \text{People} \implies266 \: \text{tickets} \\ \displaystyle100 \%\: \quad \imath \imath \implies \frac{266}{7\%} \: \: \: \: \imath \imath \\ \\ \qquad \displaystyle \qquad\rm as \: \% = \frac{1}{100} \longleftarrow \frac{266}{ \dfrac{7}{100} } \\ \\ \displaystyle \rm \: by \: simplifying \: complex \: fraction\longleftarrow 266 \times \frac{100}{7} \\ \rm reduce \: fraction \longleftarrow 38 \times 100 \\ \rm simplify \:multiplication \longleftarrow3800\end{array}[/tex]
hence,
3800 tickets were sold for the movie
Answer:
Solutions given:
[100%-97%]=266people
7% =266people
Each people is 1 ticket.
266 people =266tickets
so
7% of people=266ticket
100% of people =266/7×100=3800tickets
3800tickets were sold for the movie
(3 marks) A certain type of storage battery lasts, on average, 3.0 years with a standard deviation of 0.5 year. The battery lives are assumed normally distributed. (a) What is the probability that a given battery will last between 2.3 and 3.6 years
Answer:
0.8041 = 80.41% probability that a given battery will last between 2.3 and 3.6 years
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
A certain type of storage battery lasts, on average, 3.0 years with a standard deviation of 0.5 year
This means that [tex]\mu = 3, \sigma = 0.5[/tex]
What is the probability that a given battery will last between 2.3 and 3.6 years?
This is the p-value of Z when X = 3.6 subtracted by the p-value of Z when X = 2.3. So
X = 3.6
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3.6 - 3}{0.5}[/tex]
[tex]Z = 1.2[/tex]
[tex]Z = 1.2[/tex] has a p-value of 0.8849
X = 2.3
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{2.3 - 3}{0.5}[/tex]
[tex]Z = -1.4[/tex]
[tex]Z = -1.4[/tex] has a p-value of 0.0808
0.8849 - 0.0808 = 0.8041
0.8041 = 80.41% probability that a given battery will last between 2.3 and 3.6 years

A. 2 1/2
B. 3 Plzz help me
C. 3 1/2
D. 4
Answer:
C. 3 1/2Step-by-step explanation:
Estimate the fraction part of the number.
11/40 > 10/40 = 1/4We can estimate the fraction part as 1/2 since its greater than 1/4.
The number becomes 3 1/2.
Best choice is C
Answer:
11/40>10/40=1/4 is a part of ½
so
best estimate is 3 ½.
HELP PLEASE I WILL MARK BRAINLIEST!
Answer:
x = 35
y = 100
Step-by-step explanation:
∠AEB and ∠DEC are vertical angles because they are opposite each other; they are also equal because of this. We can write an equation to model the situation:
∠AEB = ∠DEC
50° = x° + 15°
x = 35
∠AEB and ∠AED are supplementary because the form a line; this means they add up to 180°
∠AEB + ∠AED = 180°
50° + y + 30° = 180°
y + 80° = 180°
y = 100

5y+8=-6
-8
5y=-14/5
y=-2.8
Answer:
y = - 2.8
[tex]y=-2\frac{4}{5}[/tex]
Step-by-step explanation:
5y + 8 = - 6
5y + 8 - 8 = - 6 - 8
5y = - 14
5y ÷ 5 = - 14 ÷ 5
y = - 2.8

Maria has a jewelry box and wants to increase its size. She finds one with four times the length, width, and height. How many times bigger will the volume of the box be?
Answer:
64 times bigger
Step-by-step explanation:
I will use random values for this explanation to make it more understandable.
Lets say the length of the box is 1 inch, width is 1 inch, and height is 1 inch.
The volume would be l*w*h = 1*1*1 = 1 cubic inch
If the dimensions were 4 times bigger, the length, width and height would all be 4 inches.
4*4*4 = 64 cubic inches, which is 64 times bigger than the smaller box with a volume of 1 cubic inch.
Hope this answer helped! :)

Answer:
72 in^3
Step-by-step explanation:
So to find the volume of a rectangular prism, do L * W * H for the volume. The length of the tissue box is 8, the width is 3 and the height is also 3. With this, plug these together into the equation for the volume.
8 * 3 * 3
24 * 3

It is cubed (^3) , since it is about finding how much space there is in a 3D object. When it is a 2D object such as a rectangle, it is instead squared (^2).
Nolan wants to buy carpet to cover his whole living room, except for the tiled floor. The tiled floor is 4 5\6 ft by 2 1\3 ft. Find the area the carpet needs to cover.
Answer:
11 5/18 ft squared
Step-by-step explanation:
because the floor is probably a rectangle, we can use the area formula to find the area of the carpet. the formula is
A = Length × Width
so now we plug in the numbers.
A = (4 5/6) × (2 1/3)
I'm going to simplify the numbers into an improper fraction because the numbers are in a mixed fraction format and I simply dislike it.
A = (29/6) × (7/3)
A = 203/18 ft squared
In the answer section, the numbers look different because I converted my 203/18 into a mixed number.
A = 203/18 = 11 5/18 ft squared

Answer:
D. (1.6 + 3) × (4 − 2) ÷ 2
Step-by-step explanation:
The order of operations requires that multiplication and division be done in order of appearance, left to right, before addition and subtraction. Operations in parentheses take priority.
To get 4.6, you need to add 3 to 1.6. The various forms of 3×4-2÷2 all give 12-1 = 11, not 3.
The grouping that gets it right is ...
(1.6 + 3) × (4 − 2) ÷ 2
= 4.6×2÷2
= 9.2÷2
= 4.6

Answers:
cos(A) = 0.8480
tan(B) = 1.6
=============================================
Explanation:
Before we can compute cos(A), we'll need to find the hypotenuse.
Use the pythagorean theorem.
a^2 + b^2 = c^2
8^2 + 5^2 = c^2
89 = c^2
c^2 = 89
c = sqrt(89)
The hypotenuse is exactly sqrt(89) units long.
This will allow us to find the cos(A) value
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(A) = 8/sqrt(89)
cos(A) = 0.84799830400509 which is approximate
cos(A) = 0.8480 when rounding to four decimal places
-------------------------
For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 8/5
tan(B) = 1.6

semi-circle is (dπ)*1/2 +d , but we don't need the +d since we don't have that edge so you only use (dπ)*1/2.
From there, and equalateral triangle has all the same sides, so you can assume that the two sides of the triangle added up would be 24.
Finally you add the product of (dπ)*1/2 with 24, and depending on whether it needs to be in exact terms (the decimal) or in terms of pi (the 30 one) you can change it to how it needs to be.
