Solve 13p - 2y = 14 + 10p solve for y.
Answer:
y = -7 + [tex]\frac{3p}{2}[/tex]
Step-by-step explanation:
13p - 2y = 14 + 10p
-2y = 14 - 3p
y = (14 ÷ -2) + (-3p ÷ -2)
y = -7 + [tex]\frac{3p}{2}[/tex]
The solution of equation 3p - 2y = 14 + 10p is, y = -7 + 1.5p
What is the solution of an equation?"It is a value or set of values which makes equation true after substitution."
What is equation?"It is an expression which contains an equal symbol."
Given equation: 13p - 2y = 14 + 10p
⇒ 13p - 10p -2y = 14 ..................(Subtract 10p from each side)
⇒ 3p - 2y = 14
⇒ 3p - 2y - 3p = 14 - 3p .................(Subtract 3p from each side)
⇒ -2y = 14 - 3p
⇒ -2y/(-2) = (14 - 3p)/(-2) ...............(Divide each side by -2)
⇒ y = -7 + (3/2)p
⇒ y = -7 + 1.5p
Therefore, the solution of the equation is y = -7 + 1.5p

Step-by-step explanation:
add 5 to -2 and 1/3
Answer:
2 2/3
Step-by-step explanation:
Simplify the following:
-(2 + 1/3) - -5
Hint: | Put the fractions in 2 + 1/3 over a common denominator.
Put 2 + 1/3 over the common denominator 3. 2 + 1/3 = (3×2)/3 + 1/3:
-(3×2)/3 + 1/3 - -5
Hint: | Multiply 3 and 2 together.
3×2 = 6:
-(6/3 + 1/3) - -5
Hint: | Add the fractions over a common denominator to a single fraction.
6/3 + 1/3 = (6 + 1)/3:
-(6 + 1)/3 - -5
Hint: | Evaluate 6 + 1.
6 + 1 = 7:
-7/3 - -5
Hint: | Multiply -1 and -5 together.
-(-5) = 5:

Hint: | Put the fractions in (-7)/3 + 5 over a common denominator.
Put (-7)/3 + 5 over the common denominator 3. (-7)/3 + 5 = (-7)/3 + (3×5)/3:
(-7)/3 + (3×5)/3
Hint: | Multiply 3 and 5 together.
3×5 = 15:
(-7)/3 + 15/3
Hint: | Subtract the fractions over a common denominator to a single fraction.
-7/3 + 15/3 = (-7 + 15)/3:

Find an equation in point-slope form for the line having the slope of m=4 and containing the point (5,4).
The equation in point-slope form is ___.
Answer:
y - 4 = 4(x - 5)
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of 4 and passes through the point (5,4).
We want to write this equation in point-slope form.
Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope, and [tex](x_1,y_1)[/tex] is a point.
SolvingSince we are given the slope and the point, we can immediately plug them into the formula.
Let's start with the slope; we can replace m in [tex]y-y_1=m(x-x_1)[/tex] with 4.
[tex]y-y_1=4(x-x_1)[/tex]
We can now plug 5 for [tex]x_1[/tex] and 4 for [tex]y_1[/tex].
y - 4 = 4(x - 5)
A teacher brings 4 packs of pencils to school each pack contains 12 she has 25 students in her class how many pencils can she give each student
Answer:
Each student can have 1 pencil each
Step-by-step explanation:
Since there are 4 packs of pencils with 12 pencils in each pack, you want to multiply 12 by 4 which equals 48 pencils in total. Because there are 25 students, each student can have 1 pencil. They can't have 2 pencils each though since 25 times 2 is 50 and 48 is less than 50.

What is a frequency table?A frequency table is a list of objects with the frequency of each item shown in the table.
The frequency of an occurrence or a value is the number of times it happens.
In other words, a frequency table is a table in which we have some data and their frequency.
The mode in the frequency table is the highest repeating element (most common) which is 4 in the given table.
So,
Mode = 4
The range is the complete duration of data from minimum to maximum.
Range = Maximum - Minimum
Range = 11 - 2 = 9
So to determine the range we need to subtract C from G.
Hence "The mode is the most common number of data sets, The mode in this set of data is 4, To determine the range subtract C from G, and the range will be 9".

You spend $31 on hibachi and find the service to be great. You decide to tip
20%. How much is the tip?
Answer:
$6.20 savings.
Step-by-step explanation:
Thus, a product that normally costs $31 with a 20 percent discount will cost you $24.80, and you saved $6.20. You can also calculate how much you save by simply moving the period in 20.00 percent two spaces to the left, and then multiply the result by $31 as follows: $31 x . 20 = $6.20 savings.
Answer: $6.20
Step-by-step explanation:
20% x 31 = 6.2
$6.20 is the tip.

The two triangles are congruent by the side-angle-side property.
What is congruency?The Side-Angle-Side Congruence theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one are congruent to the included angle and corresponding two sides of the other triangle.
Given that in the image of the triangle ABC and BCD,
The side AC is equal to the side CB.
AC = CB
The side EC is equal to the side CD.
EC = CD
The angles at point C are vertically opposite angles,
∠ACE = ∠BCD
Hence, from the side-angle-side property, the two triangles will be congruent with each other.

a. A point estimate of μ and its 90% margin of error.
b. A 95% confidence interval for μ.
Complete Question
From a random sample of size 18, a researcher states that (11.1, 15.7) inches is a 90% confidence interval for mu, the mean length of bass caught in a small lake. A normal distribution was assumed. Using the 90% confidence interval obtain:
a. A point estimate of [tex]\mu[/tex] and its 90% margin of error.
b. A 95% confidence interval for [tex]\mu[/tex].
Answer:
a
[tex]\= x = 13.4[/tex] . [tex]E = 2.3[/tex]
b
[tex]10.7 < \mu < 16.1 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 18
The 90% confidence interval is (11.1, 15.7)
Generally the point estimate of [tex]\mu[/tex] is mathematically evaluated as
[tex]\= x = \frac{11.1 + 15.7 }{2}[/tex]
=> [tex]\= x = 13.4[/tex]
Generally the margin of error is mathematically evaluated as
[tex]E = \frac{15.7 - 11.1}{2 }[/tex]
=> [tex]E = 2.3[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the equation for the lower limit of the confidence interval is
[tex]\= x - Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{18} } = 11.1[/tex]
=> [tex]13.4 - 0.3877 s = 11.1[/tex]
=> [tex]s = 5.932[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.96 * \frac{5.932}{\sqrt{18} }[/tex]
=> [tex]E = 2.7 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex]13.4 - 2.7 < \mu < 13.4 + 2.7 [/tex]
=> [tex]10.7 < \mu < 16.1 [/tex]
The roof of the
house is to extend
up 12 feet above the
ceiling, which is 32 feet
across, forming
isosceles triangle. Find
the length of one side of
the roof.
Answer: 124.1 feet
An isosceles triangle is one which has two equal sides and two equal angles.
Area of triangle = ab SinC where a and b are the sides, and C is the given included angle.
From the given question, a = b = 18 feet and C = 50°.
Then, Area of this part of the roof = x 18 x 18 x Sin 50°
= x 18 x 18 x 0.7660
= 162 x 0.7660
= 124.092
The area of this part of the roof is 124.1 feet.

On a certain day the chance of rain is 80% in San Francisco and 30% in Sydney. Assume the chance of rain in the two cities is independent. What is the probability that it will not rain in either city?
P(No rain in San Francisco AND No rain in Sydney)
Answer: probability not rain in San Fransisco = 100% - 80% = 20% = 0.2
probability not rain in Sydney = 100% - 30% = 70% = 0.7
probability not rain in either city (the chance of rain in the 2 cities is independent) = 0.2 * 0.7 = 0.14 = 14%

we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the amount of vinegar in tablespoons
y ----> the amount of oil in tablespoons
In this problem
The relationship between the variables x and y represent a proportional variation
The constant of proportionality k is equal to the ratio of the recipe
so
substitute
The linear equation is equal to
