Which of the following expressions is equal to In (4y?)?
Answer:
[tex]ln(4)+2\,\,ln(y)[/tex]
(the first option of the list)
Step-by-step explanation:
Using the properties of logarithms (first the logarithm of a product and then the logarithm of a power, we write:
[tex]ln(4\,y^2)=ln(4)+ln(y^2)=ln(4)+2\,\,ln(y)[/tex]
which agrees with the first option in the list of possible answers.

You hold a tape measure along the width of a picture frame. One end of the frame is 2 3/4 inches and the other end is at 10 7/16 inches. How wide is the frame in between
Answer:
Width = [tex]7\frac{11}{16}[/tex] inches
Step-by-step explanation:
Given
[tex]End_1 = 2\frac{3}{4}[/tex]
[tex]End_2 = 10\frac{7}{16}[/tex]
Required
Determine the width of frame in between
To do this, we simply calculate the difference between both ends:
i.e.
[tex]Difference = End_2 - End_1[/tex]
This gives:
[tex]Difference = 10\frac{7}{16} - 2\frac{3}{4}[/tex]
Convert to improper number
[tex]Difference = \frac{167}{16} - \frac{11}{4}[/tex]
Take LCM
[tex]Difference = \frac{167 - 44}{16}[/tex]
[tex]Difference = \frac{123}{16}[/tex]
[tex]Difference = 7\frac{11}{16}[/tex]
Hence, the width of the frame is [tex]7\frac{11}{16}[/tex] inches

Write an expression for the area and perimeter for the figure shown
Answer:
Area = 3x² + 7x + 3
Perimeter = 8x + 8
Step-by-step explanation:
The figure can be decomposed into two: a large rectangle and a smaller rectangle.
✍️Dimensions of the large rectangle:
Length = (x + 1) + x = x + 1 + x = (2x + 1)
Width = (x + 3)
Area = length × width
Area = (2x + 1)(x + 3)
Expand
2x(x + 3) +1(x + 3)
2x² + 6x + x + 3
Area = 2x² + 7x + 3
✍️Dimensions of the large rectangle:
Length = x
Width = x
Area = length × width
Area = x × x = x²
✍️Area of the figure = area of the large rectangle + area of the smaller rectangle
Area of the figure = (2x² + 7x + 3) + x²
Area of the figure = 2x² + x² + 7x + 3
✅Area = 3x² + 7x + 3
✍️ Perimeter of the figure = sum of the length of all sides of the figure = (x + 3) + x + x + x + (x + 1) + (x + 3) + (x + 1) + x
✅Perimeter = 8x + 8
It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate: How many pounds of
potatoes are needed to make 50 pounds of mashed potatoes?
Answer:
33.333.... or 33 33/100

The polynomial –16t2 + vt + h0 models the height, in feet, of a ball t seconds after it is thrown. In this polynomial, v represents the initial vertical velocity of the ball and h0 represents the initial height of the ball. Min throws a baseball from a height of 6 feet with an initial vertical velocity of 30 feet per second. Which polynomial models the height of the ball, in feet?
Answer: -16t^2 + 30t + 6
Step-by-step explanation: just substitute it...also did Edge
The height of the ball given by the polynomial describes the projectile
motion of the ball.
The polynomial that models the height of the ball Min throws, in feet is presented as follows;
h(t) = -16·t² + 30·t + 6Reasons:
The given polynomial for the height of the ball is; h(t) = -16·t² + v·t + h₀
Where;
v = The initial velocity of the ball
h₀ = The initial height
t = The time in seconds
The polynomial that models the height of the ball Min throws is given by substitution of the values of v, h₀, in the above equation as follows;
The height of the ball is; h(t) = -16·t² + 30·t + 6

I NEED AN EXPLANATION NOT JUST THe ANSWERS PLEASE! I will give brainliest based on how good the explanation is. Thanks so much :)
Answer:
Question 1: $2 / Question 2: $7.5
Step-by-step explanation:
$5 is the original 100%, what Noah has, and if Elena has 40% of what Noah has, then they have 0.4 the amount, 5x0.4=2. It should be the same for Diego but instead 150%, or 5x1.5, which equals 7.5

A die is rolled. If it rolls to a 1, 2, or 3 you win $2. If it rolls to a 4, 5, or 6 you lose $1. Find the expected winnings.
a) $0.50
b) $3.00
c) $1.50
d) $1.00
Answer:
A. $0.5
Step-by-step explanation:
In this question half of the time your winning is 2 dollars and also the other half of the time your loss is one dollar
The expectation is that after you must have had 2 rolls you would get 2 dollars once and also you are going to lose 1 dollar once. So what you won overall would be 1 dollar.
So the correct answer would be gotten from $1/2rolls
= $0.50

Find all 3-digit numbers which are 19 times the sum of their digits.
Answer:
The 3 digit numbers are;
171, 152, 133, 114, 285, 266, 247, 228, 209, 399
Step-by-step explanation:
Let the 3 digit number be xyz
Since x is the Hundreds digit, y is the tens digit and z is the unit digit, we have;
100x, 10y and z
We are told the sum of this is equal to 19 times the sum of their digits.
Thus;
100x + 10y + z = 19(x + y + z)
100x + 10y + z = 19x + 19y + 19z
This gives;
81x - 9y - 18z = 0
Divide through by 9 to get;
9x - y - 2z = 0
x = (2z + y)/9
Now, we will need to select values of z and y between 0 to 9 in such a way that (2z + y) is divisible by 9 and in such a way that x > 0 but ≤ 10
The possible solutions are;
At z = 1, y = 7 and x = 1
At z = 2, y = 5 and x = 1
At z = 3, y = 3 and x = 1
At z = 4, y = 1 and x = 1
At z = 5, y = 8 and x = 2
At z = 6, y = 6 and x = 2
At z = 7, y = 4 and x = 2
At z = 8, y = 2 and x = 2
At z = 9, y = 0 and x = 2
At z = 9, y = 9 and x = 3
Compiling all these, the 3 digit numbers are;
171, 152, 133, 114, 285, 266, 247, 228, 209, 399
Find the sum plz.
3 3/15 + 4 2/5
Answer:
38/5
Step-by-step explanation:
15 x 3 = 45 + 3 = 48/15
then 4 + 5 = 20 + 2 = 22/5
22/5 + 48/15 = ?
find the common denominator
15 ÷ by 3 so you do the same to the numerator so, 48 ÷ 3 = 16
then keep the 22 and 16 and put it as 16/5 and 22/5 and add them to get 38/5

solve for x no work needed
Answer:
[tex]\huge\boxed{82 \textdegree}[/tex]
Step-by-step explanation:
We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:
[tex]31+x+(x-15) = 180[/tex]
Let's solve for x.
Combine like terms:
[tex]31+2x-15=180[/tex]
Add 15 to both sides:
[tex]31+2x=195[/tex]
Subtract 31 from both sides:
[tex]2x=164[/tex]
Divide both sides by 2:
[tex]x= 82[/tex]
So x is 82°.

An Internet service provider sampled 540 customers and found that 75 of them experienced an interruption in high-speed service during the previous month. (a) Find a point estimate for the population proportion of all customers who experienced an interruption. DO NOT ROUND the answer. (b) Construct a 90% confidence interval for the proportion of all customers who experienced an interruption. Round your answer to 3 decimal places. (c) Estimate the sample size needed so that a 95% confidence interval will have a margin of error of 0.03.
Answer:
a) point estimate for the population proportion of all customers who experienced an interruption
E = 0.029
b)
90% confidence interval for the proportion of all customers who experienced an interruption
(0.11441 , 0.16319)
C)
Size of the sample 'n' = 509
Step-by-step explanation:
Step(i):-
a)
An Internet service provider sampled 540 customers and found that 75 of them experienced an interruption in high-speed service during the previous month.
Sample proportion
[tex]p = \frac{x}{n} = \frac{75}{540} = 0.1388[/tex]
The point estimate of all customers who experienced an interruption
[tex]E = \frac{Z_{\alpha }\sqrt{p(1-p)} }{\sqrt{n} }[/tex]
Level of significance
Z₀.₀₅ = 1.96
[tex]E = \frac{1.96\sqrt{0.138(1-0.1388)} }{\sqrt{540} }[/tex]
E = 0.029
b)
90% confidence interval for the proportion of all customers who experienced an interruption
[tex]( p - Z_{0.10} \sqrt{\frac{p(1-p)}{n} } ,p + Z_{0.10} \sqrt{\frac{p(1-p)}{n} })[/tex]
[tex]( 0.1388 -1.645 \sqrt{\frac{0.1388(1-0.1388)}{540} } ,0.1388 + 1.645 \sqrt{\frac{0.1388(1-0.1388)}{540} })[/tex]
( 0.1388 - 0.02439 , 0.1388 + 0.02439)
(0.11441 , 0.16319)
c)
Margin of error
[tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]
[tex]0.03 = \frac{1.96 \sqrt{0.1388(1-0.1388)} }{\sqrt{n} }[/tex]
√n = 22.58
Squaring on both sides, we get
n = 509
