Step-by-step explanation:
James and his family spend a morning picking peaches. They fill several bags. This line plot shows the weight of each bag.
How many more pounds does one of the heaviest bags weigh than one of the lightest bags?
The number of pounds that one of the heaviest bag weighs more than one of the lightest bag in the given line plot is: 1½
What is a Line Plot?In a line plot, frequency of a data point is either represented by a dot or a mark.
In the line plot given:
Heaviest bag weighs 5¾
Lightest bag weighs 4¼
The difference between the heaviest and lightest bag = 5¾ - 4¼
= 23/4 - 17/4
= (23 - 17)/4 = 6/4 = 3/2
= 1½
The heaviest bag weighs 1½ pounds than the lightest bag.

Kenzie bought 12 belts for $54 write an equation that shows the relationship between the numbers of belt B and C the total cost for the belts
Answer:
$4.50B = C
Step-by-step explanation:
Kenzie bought 12 belts for $54, which means that each belt costs $4.50.
If b=number of belts, c=the total cost, and x=the cost of one belt, the equation would be:
b(x)=c,
so:
12*$4.50=$54
OR
$4.50B=C
hope that helps! good luck!
Answer:
C = 4.50B
Step-by-step explanation:
Finding the cost of a belt
Total cost / Number of belts$54 / 12$4.50Therefore, the relation between B, the number of belts, and C, the total cost, will be :
C = 4.50BHELP PLS

Solve the quadratic equation by completing the square and applying the square root property.
u2 + 20u + 101 = 0
Answer: u = -10 + i or u = -10 - i
Step-by-step explanation:
[tex]\begin{aligned}&u^{2}+20 u+101=0 \\&u^{2}+10^{2}+2 \times 10 \times 6 u+101-1000=0 \\&(u+10)^{2}=-1\end{aligned}[/tex]

Answer:
[tex]u = - 10 + i, \: \: - (10 + i)[/tex]
Step-by-step explanation:
[tex] {u}^{2} + 20u + 101 = 0 \\ \\ \implies \: {u}^{2} + 20u + 100 + 1 = 0 \\ \\ \implies \: {u}^{2} + 20u + {(10)}^{2} + 1 = 0 \\ \\ \implies \: {(u + 10)}^{2} = - 1 \\ \\ \implies \: {u + 10} = \pm\sqrt{ - 1} \\ \\ \implies \: {u} = \pm \: i - 10\\ \\ u = i - 10 \: \: or \: \: u = - i - 10 \\ \\ u = i - 10 \: \: or \: \: u = - (10 + i) \\ \\ u = - 10 + i, \: \: - (10 + i)[/tex]
x/50=40/64 solve for x
X/50 = 40/64
To find x cross multiply:
64 * x = 50 * 40
Simplify:
64x = 2000
Divide both sides by 64:
X = 31.25
Answer:
x = [tex]\frac{125}{4}[/tex]
Step-by-step explanation:
[tex]\frac{X}{50}[/tex] = [tex]\frac{40}{64}[/tex]
Divide both sides of the equation by the coefficient of variable
X = [tex]\frac{40}{64}[/tex] x 50
Simplify the fractions:
x = [tex]\frac{5}{4}[/tex] x 25
Write as a single fraction
x = [tex]\frac{5*25}{4}[/tex]
Calculate the product:
x = [tex]\frac{125}{4}[/tex]

Given that some normally distributed data has a mean of 857.518 and a standard
deviation of 113.181. What is the probability that a randomly sampled datapoint wil
be greater than 1007.174?
Answer:
10%
Step-by-step explanation:
(1007.174 - 857.518) / (113.181) means that
1007.174 is 1.32 standard dev ABOVE the mean
z-score = .9066 from z-score chart
means 90% are less and ~~ 10% are this value or more

please help find x and mDE
Answer:
x = 16
measure of Arc(DE) = 167°
Step-by-step explanation:
Since the arc EFG make a straight angle, we can infer;
180° = Arc(EF) + Arc(FG)
180° = (x-3)° + (12x - 25)°
180° = 13x - 28
208 = 13x
16 = x
Arc GF and DE are vertical angles so if you find the measure of Arc GF then it's the same as measure of Arc DE
mDE = mGF
mDE = 12x - 25
mDE = 12(16) - 25
mDE = 192 - 25
mDE = 167°

Express the following expressions in terms of x, y, and z
(1) log (14/3)
(2) log 0.3
(3) log 10.5
Answer: See below
Step-by-step explanation:
Answer (1)
We must break down the expressions into factors. That is:
[tex]\begin{align} \log 12&=\log 4\times 3=\log 2^2\times 3\\ \log 12&=\log 2^2+\log 3=2\log 2+\log 3=2x+y\\ \end{align}[/tex][tex]\log \frac{14}{3}&=\log 14-\log 3 \\ =\log 2\times 7-\log 3\\ \\\log \frac{14}{3}& =\log 2+\log 7-\log 3 \\ =x+z-y\\[/tex]
Answer (2)
[tex]\log 0.3 &=\log \frac{3}{10} \\ \\ =\log 3-\log 10 \\=y-1[/tex]
Answer (3)
[tex]\log 10.5& \\ =\log \frac{21}{2} \\=\log 21-\log 2\\ \\ \log 10.5& \\ =\log 3\times 7-\log 2\\=\log 3+\log 7-\log 2\\=y+z-x[/tex]
