Step-by-step explanation:
we need to bring them to the same denominator. in this case : 10
so, 1/10 of everything are red.
1/5 = 2/2 × 1/5 = 2/10 of everything are blue.
so, we now just add these two :
1/10 + 2/10 = 3/10
so, 3/10 are red and blue (rather red or blue, because none are red and blue)..

The probability that X is greater than 53
What is probability ?
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
Formula for calculating the standard score or z score:
z = x-μ/σ, where:
z is the standard score
x is the raw score
μ is the population mean
σ is the population standard deviation
In this question: μ = 61 and σ = 8
The score is greater than 53
Let’s calculate the z score, for x = 53 and then find the probability for x greater than 53
z = (53 - 61)/8
= -8 / 8
= -1

○ (ƒ − g)(x) = −x² + 11x − 4
○ (ƒ − g)(x) = −x² — x^4
○ (ƒ − g)(x) = 7x² + x − 4
○ (ƒ − g)(x) = x² − 11x +4

What is the product of 6/sqrt(3) and 3/sqrt(6) in simplest radical form?
The answer is 54√2.
What is simplest radical form?
The radical form is fairly simple. It refers to the form of numbers or algebraic expressions below radicals. However, this can be improved by manipulating numbers or algebraic expressions in their radical form into what is called the simplest radical form. There are no longer any square, cube, fourth, or other roots to be found when a radical is simplified into its simplest possible form. It also entails eliminating any radicals from the fraction's denominator.
SSolving the equations,
=6√3 × 3√6
=( 6 × 3 )√( 6 × 3 )
=18√18
= 18√(2×9)

What is probability?Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A probability value between 0 and 1 represents an occurrence.
The four primary categories of probability are axiomatic, classical, empirical, and subjective. Since probability is the same as possibility, you might argue that it is the likelihood that a specific event will occur.
Given that,
μ = 27
σ = 3
n = 60
As we know,
= p ( 26 < x(avg.) < 26.8 )
= p (26 - 27 / 0.3873 ) < ( x(avg.) - μ(avg.)x /σx(avg.) ) < (26.8- 27/0.3873)
= p ( -1/ 0.3873 < z < -0.2 / 0.3873 )
= p ( -2.5820 < z < -0.5164 )
= p ( z < -0.5164) - p ( z < -2.5820 )
Using z table, we get -
= 0.3028- 0.0049
= 0.2979

There is an 8.1% probability that any given distance will exceed 212.50 cm.
What is probability?A probability is a numerical representation of the likelihood or chance that a specific event will take place.
Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
I frequently remind kids that we can express probabilities as ratios, percentages, fractions, or decimals so they are aware of the variety of ways we express odds.
So, the probability that the individual distance is greater:
z = 212.50-200/8.9 = 1.4
Looking up 1.4 in the normal distribution table:
P(z>1.4) = 1 - 0.9192 = 0.0808
= 8.1%
Therefore, there is an 8.1% probability that any given distance will exceed 212.50 cm.

Select the correct answer. What would be the value of $150 after eight years if you earn 12 percent interest per year? a. $371. 39 b. $415. 96 c. $465. 88.
The value will be $371.39.
What is compound interest?Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.
The formula to calculate the compound amount after t years is given by :-
A =P [tex](1 + R)^{T}[/tex]
where the interest rate is r and P represents the principal amount.
Given: $150 is the principal sum.
Interest is charged at a rate of 12%/0.12
A = 150 will be the amount compounded after 8 years.
A = 150 [tex]( 1 + 12 )^{8}[/tex]
A =371.3944
A = $371.39
Hence, the value of $150 after eight years if you earn 12 percent interest per year would be $371.39.

Find the equation of the line that is parallel to the line y = 5x + 10 and passes through the point (-6, -10). Write the equation in slope-intercept form.
Example 2. Find each measure.
The measure of angle ∠C = 35°, 2x = 50° and x = 25°.
What are angles?In Euclidean geometry, an angle is made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively.
Angles can be formed by two rays in the plane where they are placed.
Additionally, when two planes overlap, angles are created.
Dihedral angles are what they are called.
So, m∠ABC:
We know that ∠C in triangle ABC = 180 - 145 = 35°
Now, the measure of m∠ABC:
95 + 35 + 2x = 180
130 + 2x = 180
2x = 180 - 130
2x = 50°
x = 50/2
x = 25°
Therefore, the measure of angle ∠C = 35°, 2x = 50° and x = 25°.

The speed of Zihao to open the door, when toilet is on 25 m in front of the door for 5 sec is 5m/sec.
What is meant by speed, distance and time?The formula used to explain the relationship between speed, distance, and time is speed distance time. That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs. For instance, the length of the line segment that connects two points equals the distance between them. The formula for finding the distance between two points in a two-dimensional plane—which can be expanded to discover the distance between two points in a three-dimensional plane as well—is derived using the Pythagoras theorem.

Technology required. A 6 oz cylindrical can of tomato paste needs to have a volume of
178 cm. The current can design uses a radius of 2.75 cm and a height of 7.5 cm. Use
graphing technology to find a cylindrical design that would have less surface area so
each can uses less metal.
The required parameters of a smaller surface area and a smaller amount of metal per can are a radius of 3.05 cm and a height of 6.09 cm.
What is surface area?The measurement that indicates the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. A three-dimensional shape's surface area is the sum of all of its faces. Finding the area of each face and adding them together gives us the surface area of a form.
Here,
V=πr²h
178=πr²h
πrh=178/r
S=2πr²+2πrh
S=2πr²+2*(178/r)
S=2πr²+356/r
S'=4πr-356/r²
S'=0
4πr=356/r²
r³=356/4π
r³=28.343
r=3.05 cm
h=178/πr²
h=178/(3.14*3.05*3.05)
h=178/29.23
h=6.09 cm
