A contestant in a weight loss competition wants to lose an average of at least 8 pounds
per month during a 5-month period. In the first 4 months they have lost the following
weight: 12 lbs, 9 lbs, 5 lbs, 8 lbs. How many pounds must the contestant lose in the fifth
month to meet the goal?
Answer:
In the fifth month the contestant must lose 6 pounds of weight.
Step-by-step explanation:
Given that the contestant wants to lose an average of 8 pounds of weight per month for 5 months, taking into account that in the first 4 months of the contest he lost 12, 9, 5 and 8 pounds respectively, to determine how much weight he should lose in the fifth month the following calculation must be performed:
8 x 5 = 40 (pounds to lose)
12 + 9 + 5 + 8 = 34 (pounds lost)
40 - 34 = 6
Therefore, in the fifth month the contestant must lose 6 pounds of weight.

Jason surveyed 90 people on their preference of fruits or vegetables complete the two way frequency table
The values in the missing places are 26, 52, 14, 40 and 50
What is a frequency table?A table drawn up to show the distribution of the frequency of occurrence of a given characteristic according to some specified set of class intervals.
Given is a frequency table with some missing places,
For every missing places, we just need to add or subtract from the total.
Types of food Age
child adult (18+) Total
Fruit 26 26 52
Vegetable 14 24 38
Total 40 50 90
First missing place = 50-24 = 26
Second missing place = 26+26 = 52
Third missing place = 38-24 = 14
Fourth missing place = 26+14 = 40
Fifth missing place = 90-40 = 50
Hence, The values in the missing places are 26, 52, 14, 40 and 50

Given that a varied inversely as b, and b varies directly as the square of c, and a=1 when c=3 find the value of a when c=1/3
Please I need solvings for this thanks
Answer:
81
Step-by-step explanation:
When two variables have direct variation, as one variable increases the other variable increases or as one variable decrease, the other decrease. While for an inverse variation, as one variable increase, the other variable decrease or as one variable decrease, the other variable increase.
Given that a ∝ 1/b. Also b ∝ c².
Hence if k is the constant of proportionality, we have:
a ∝ 1 / c²
a = k / c²
When a = 1, c = 3, hence:
1 = k / 3²
k = 1 * 3²
k = 9
Therefore:
a = 9 / c²
When c = 1/3
a = 9 / (1/3)²
a = 9 / (1² / 3²)
a = 9 / (1 / 9)
a = 9 * 9
a = 81

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.
Part A:
[tex]2x^2+5=13[/tex]
Part B:
[tex]2x^{3} - 13 = 5[/tex]
Answer:
A) ±2
B) 2.08
Step-by-step explanation:
A) Given the equation
2x² + 5 = 13
Add the additive inverse of 5 to both sides
2x² + 5 + (-5) = 13 + (-5)
2x² + 5 - 5 = 13 - 5
2x² = 8
x² = 4
x= ±√4
x = ±2
Hence the value of x is ±2
b) 2x³-13 = 5
Add the additive inverse of -13 to both sides
2x³-13 + 13 = 5 +13
2x³ = 18
x³ = 18/2
x³ = 9
x = ∛9
x= 2.08
Hence the value of x is 2.08

Answer:
A. y = 91.1765x - 346.5708B. 64 lbsStep-by-step explanation:
Part AUse the data in the table to get the best fit line, with equation:
y = mx + bTo do so follow the steps:
1. Let the Height be x and the Weight be y
Sum x and y
∑x = 5.3 + 5.4 + 5.3 + 6 = 22∑y = 140 + 150 + 130 + 200 = 6202. Sum x² and xy
∑x² = 5.3² + 5.4² + 5.3² + 6² = 121.34∑xy = 5.3*140 + 5.4*150 + 5.3*130 + 6*200 = 34413. Calculate m, considering n = 4 (number of data values)
m = (n∑xy -∑x∑y)/(n∑x² - (∑x)²) = (4*3441 - 22*620)/(4*121.34 - 22²) = 124/1.36 = 91.17654. Calculate b:
b = (∑y - m∑x)/n =(620 - 91.1765*22)/4 = -1385.883 /4 =-346.4708We got the best line fit formula:
y = 91.1765x - 346.5708Part BFinding y for x = 4.5:
y = 91.1765*4.5 - 346.5708 = 63.72345 ≈ 64 lbsWhat point on the graph represents the unit cost at Florentino’s? What is the unit cost?

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.
A) 7.2
B) 6.0
C) 2.8
D) 6.3
Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
Step-by-step explanation:
Given
L(3,4)M(1,-2)Determining the length of LM
(x₁, y₁) = (3, 4) (x₂, y₂) = (1, -2)The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)
[tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]
[tex]=\sqrt{2^2+6^2}[/tex]
[tex]=\sqrt{4+36}[/tex]
[tex]=\sqrt{40}[/tex]
[tex]=\sqrt{4\times 10}[/tex]
[tex]=\sqrt{2^2\times \:10}[/tex]
[tex]=2\sqrt{10}[/tex]
[tex]=6.3[/tex]
Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
