Answer:
6 3/5 points
Step-by-step explanation:
Steve is creating a web page.
Step 1
He starts with a font of 5 9/10 points and decreases it by 1/2.
Hence: Current font
= 5 9/10 - 1/2
= 5 + ( 9/10 - 1/2)
Lowest common denominator
= 10
= 5 + (9 - 5/10)
= 5 + 4/10
= 5 + 2/5
= 5 2/5 points
Step 2
He decreases it again by 6/10 points.
Current fonts
= 5 2/5 - 6/10
= 5 + ( 2/5 - 6/10)
Lowest common denominator
= 10
= 5 + (4 - 6/10)
= 5 + (-2/10)
= 5 - 1/5
= 4 4/5 points
Step 3
Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points.
New font
= 4 4/5 points + 1 4/5 points
Lowest common denominator = 5
= 4 + 1 + (4/5 + 4/5)
= 5+ ( 4 + 4/5)
= 5 +(8/5)
= 6 3/5 points
The best estimate of the font's final size is 6 3/5 points

An express train travelled at a certain average speed from Town X to Town Y which was
150 km away. It then continued its journey to Town Z at an average speed 20 km/h faster than
its initial average speed. Town Ywas 200 km from Town Z. If it took the same time to travel for
both parts of the journey, what was the train's average speed for the first part of the journey?
Answer:
60 km/hr
Step-by-step explanation:
Let the speed at the initial average speed from Town X to Town Y be a.
We are told that it journeyed to Town Z at an average speed 20 km/h faster than its initial average speed. Thus, its average speed here is (a + 20) km/hr.
Town Y was 200 km from Town Z.
Thus, time spent here is;
t_2 = 200/(a + 20)
Time from X to Y is; t_1 = 150/a
We are told that it took the same time to travel for both parts of the journey.
Thus; t_1 = t_2
150/a = 200/(a + 20)
Cross multiply to get;
150(a + 20) = 200a
150a + 3000 = 200a
200a - 150a = 3000
50a = 3000
a = 3000/50
a = 60 km/hr
Please help me answer this question thank you.
Answer:
122°
Step-by-step explanation:
10a + 2° + 5a - 2° = 180° [ being linear pair ]
15a = 180°
a = 180° / 15
a =12°
Now
<XYQ = 10a + 2° = 10 * 12° + 2° = 120° + 2° = 122°

how do i solve -3x + 2y = -4
Answer:
y= 3/2 x -2
Step-by-step explanation:
I guess you want to find the y=mx+b form
So you do +3x on both sides which will gave you: 2y= 3x-4
Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2
So 3/2 is the fraction like the answer above and -4/2 = -2
Hope that helps :)

Combine like terms to create an equivalent expression. 4\left(1.75y-3.5\right)+1.25y4(1.75y−3.5)+1.25y
Answer:
8.25y + 14
Step-by-step explanation:
Given the expression
[tex]4\left(1.75y-3.5\right)+1.25y[/tex]
We are to simplify it as shown
Open the parenthesis
4(1.75y) - 4(3.5) + 1.25y
7y - 14 + 1.25y
Collect the like terms
7y + 1.25y - 14
8.25y + 14
Hence the required expression is 8.25y + 14

Question 6
A machine is used to fill bags with a popular brand of trail mix. The machine is calibrated so the distribution of the weights of the bags of trail mix is normal,
with mean 240 grams and standard deviation 3 grams. Of the following, which is the least weight of a bag in the top 5 percent of the distribution?
Answer:
D. 246 grams
Step-by-step explanation:
invnorm(.95, 240, 3) is around 244 and the question is asking for the least weight of a bag in the top 95%, so the smallest number within
a. 234
b. 240
c. 243
d. 246
e. 248
is d.
The distribution of the mix follows inverse normal distribution
The least weight of a bag in the top 5% is 246 grams
The given parameters are:
[tex]\mathbf{\mu = 240}[/tex] ---- population mean
[tex]\mathbf{\sigma = 3}[/tex] ---- population standard deviation
To get the least weight of a bag in the top 5%, we make use of inverse normal distribution.
So, we have:
[tex]\mathbf{Least = invNorm(p,[\mu,\sigma])}[/tex]
Being in the top 5% means that:
p = 1 - 5%
p = 1 - 0.05
p = 0.95
So, we have:
[tex]\mathbf{Least = invNorm(0.95,240,3)}[/tex]
From the inverse normal calculator, we have
[tex]\mathbf{Least = 246}[/tex]
Hence, the least weight is 246 grams

Answer:
Option D is correct .
Step by step explanation:
A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.
So for finding its inverse , exachange x with y .
⇒ g(x) = -2x⁵ - 2 .
Let g(x) = y ,
⇒ y = -2x⁵ - 2 .
Replace x with y ,
⇒ x = -2y⁵ - 2
⇒ x + 2 = -2y⁵
⇒ y⁵ = x+2 / -2
⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)
⇒ y⁵ = -x - 2/ 2
⇒ y = ⁵√ [ ( -x -2)/2 ]
Hence the inverse of the function is ,
[tex]\boxed{\red{\bf f^{-1}(x)=\sqrt[5]{\dfrac{-x-2}{2}}}}[/tex]
Hence the correct option is (D) .I don't understand the way they've arranged the statement...
