Answer:
(a). [tex]\frac{33}{40}[/tex] ; (b). 33 to 40
Step-by-step explanation:
Use "magic fraction" [tex]\frac{Part}{Whole}[/tex]
(a). Distance covered by runner is 33 yards
Whole distance is 40 yards
The portion of the race that the runner has completed is
[tex]\frac{33}{40}[/tex]
(b). The portion of the race that the runner has completed is 33 to 40
The display gives sale prices for 40 houses in Ames, Iowa sold during a recent month. The mean sale price was $203,388 with a standard deviation of $87,609. Find the percentile of the house indicated in red on the dotplot
Answer:
Step-by-step explanation:
The percentile of the house indicated in red on the dotplot is "[tex]62^{nd}[/tex] percentile".
Given values are:
Number of houses,
40Mean sale price,
μ = $203,388Standard deviation,
σ = $87,609Now,
→ [tex]z = \frac{230,000-203,388}{87,608}[/tex]
→ [tex]= \frac{26,612}{87,608}[/tex]
→ [tex]=0.30[/tex]
By using the table, we get
→ [tex]= 0.6179[/tex]

Solve the compound inequality
Answer:
4/7 > x > -11/7
Step-by-step explanation:
First, add -4/3 to all parts
then divide all parts by -7/3
so, We need to separate it into two inequalities
[tex] \frac{4 - 7x}{3} > 0[/tex]
[tex] \frac{4 - 7x}{3} < 5[/tex]
then we solve for x,
[tex] \frac{4 - 7x}{3} > 0 = x < \frac{4}{7} [/tex]
[tex] \frac{4 - 7x}{3} < 5 = x > - \frac{11}{7} [/tex]
so we ended up like this
[tex]x = ( - \frac{11}{7} \frac{4}{7})[/tex]

Answer:
y = 2x + 8
Step-by-step explanation:
You can see that the line crosses the y-intercept at 8 which is point (0, 8). From that y-intercept point you rise 2 then run 1 to get to point (2, 12), this rise over run is your slope 2/1 or simply 2.
y = mx + b
m is your slope
b is your y-intercept
y = 2x + 8

Lon is selling gift baskets at a craft fair. His costs are $75 for the table and $12 per basket. He sells each basket for $20.
1. Let b equal the number of baskets. Which expression represents Lon's costs? *
A- 12b - 75
B- 12b +75
C- 20b - 75
D- 20b -12b
2. How many baskets must be sold to make a profit? Solve this inequality to find out. 20b > 12b + 75 (hint: remember it's asking to make a profit) *
A- fewer than 9
B- fewer than 10
C- at least 10
D- more than 12
Answer:
1. B
2. D
Step-by-step explanation:
1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75
2. He needs a profit and the only way he could make that profit is if he sells more than 12.
20b > 12b + 75
20 (12) > 12 (12) + 75
240 > 140 + 75
240 > 215

5. The denominator of a fraction exceeds the numerator of a fraction by 25.
The value of the fraction is 3/8. Find the number
9514 1404 393
Answer:
15/40
Step-by-step explanation:
The difference between denominator and numerator in 3/8 is 8-3 = 5. In order to get an equal-value fraction with that difference being 25, each of the numbers must be multiplied by 5:
3/8 = 15/40
The number is 15/40.

solve as multi-step eqaution 24(34 + r) = 1200
The value of 'r' in the expression 24(34 + r) = 1200 is 16.
What are the basic properties of arithmetic laws of operations?There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, An expression 24(34 + r) = 1200.
First, we'll distribute LHS,
24×34 + 24×r = 1200.
816 + 24r = 1200.
24r = 1200 - 816.
24r = 384.
r = 384/24.
r = 16.

Bonus: ∠2 = 112°, ∠4 = 112°, ∠8 = 112°, ∠1 = 68°, ∠3 = 68°, ∠5 = 68°, ∠7 = 68°
Step-by-step explanation:
1. Angles 1 and 2 are supplementary because they form a straight line (180° angle) together.
2. Angles 1 and 5 are corresponding because their places (and angle measures) match.
3. Angles 2 and 5 are not alternate exterior angles because angle 5 is not on the outside area of the parallel lines.
4. Angles 4 and 6 are alternate interior angles because they are on opposite sides of the transversal and are both in the inside area of the parallel lines.
5. Angles 7 and 2 are not corresponding because their places (and angle measures) do not match.
6. Angles 3 and 6 are interior angles on the same side of the transversal because they are both in the inside area of the parallel lines and are on the same side of the transversal.
7. Angle 3 is not congruent to angle 8 because they do not have the same angle measures.
8. Angles 3 and 7 are corresponding angles because their places (and angle measures) match.
9. Angles 8 and 2 are alternate exterior angles because they are on opposite sides of the transversal and are outside areas of the parallel lines.
Bonus: If angle 6 has a measure of 112°, then the angle that supplements it has a measure of 68° (112 + 68 = 180). It also goes for the other angles that are congruent to angle 6.
