Complete question :
Dairy farmers are aware there is often a linear relationship between age, in years, of a dairy cow in the amount of milk produced, in gallons per week. The least squares regression line produced from a random sample is milk=40.8-1.1(Age). Based on the model, what is the difference in predicted amounts of milk produce between a cow of five years in a cow of 10 years?
Answer:
A cow of five years is predicted to produce 5.5 more gallons of milk per week.
Step-by-step explanation:
Given the regression model :
milk=40.8-1.1(Age)
Milk produced by 5 year old cow using the model :
Milk produced = 40.8 - 1.1(5)
Milk produced = 40.8 - 5.5
Milk produced = 35.3
Milk produced by 10 year old cow using the model :
Milk produced = 40.8 - 1.1(10)
Milk produced = 40.8 - 11
Milk produced = 29.8
Difference in volume of milk produced :
Age 5 milk producrion- Age 10 milk production :
35.3 - 29.8
= 5.5
Answer:
Answer B
Step-by-step explanation:
The difference of 5 years produces a 5.5 gallon per week difference in favor of the younger cow.
Four cards will be dealt off the top of a well-shuffled deck. There are two options. (i) To win $10 if the first card is club and the second is a diamond and the third is a heart and the fourth is a spade. (ii) To win $10 if the four cards are of four different suits. Compute the probability of winning $10 for each case. Which option is better
Answer:
0.0043957 ; 0.105498 ; 2nd option is better
Step-by-step explanation:
Option 1:
First card :P(club) = 13/52
Second card: P(diamond) = 13/51
Third card : P(heart) = 13 / 50
Fourth card: P(spade) = 13/49
Hence,
P(club, diamond, heart, spade) = (13/52) * (13/51) * (13/50) * (13/49) = 0.0043957
Probability of winning $10 = 0.0043957
2nd option:
P(card of different suit) [order of arrangement does not matter]
(13C1 * 13C1 * 13C1 * 13C1) / 52C4
= 28561 / 270725
= 0.105498
Probability of winning $10 = 0.105498
Because the probability of winning for the second option is higher than for the first option, then the second option is better.

Let C = total cost, and t = number of t-shirts. Using the following equation C = 4t + 160, how much will it cost for 30 t-shirts?
Answer:
$280
Step-by-step explanation:
4(30)+160
120+160
280
Answer:
280 (see below)
Step-by-step explanation:
If C = total cost and t = number of t-shirts, then for 30 shirts, plug the amount of shirts into the variable for shirts in the equation given:
C = 4t + 160
C = 4 (30) + 160
C = 120 + 160
C = 280

why is 4320 divisible by 3, 9, and 10
Answer:
One integer A is divisible by another integer B,
if after dividing them, A ÷ B, the remainder is zero.
4,320 is divisible by 10, if there is an integer 'n' such that 4,320 = 'n' × 10.
Notice that dividing our numbers leaves no remainder:
4,320 ÷ 10 = 432 + 0;
So, 4,320 = 432 × 10;
=> 4,320 is divisible by 10.
10 is called a divisor (a factor) of 4,320.
10 | 4,320
The shorthand notation A | B means A divides B.
4,320 is a multiple of 10.
Note that this is also the first step of the Euclidean Algorithm, where the division of the numbers stops when a remainder equal to zero is reported.
4,320 is divisible by 10:
10 | 4,320

What is percentage?Percentage, a relative value indicating hundredth parts of any quantity.
A percentage is a number or ratio that can be expressed as a fraction of 100.
According to the question
Joyce paid $50 for an item at the store that was 45 percent of the original price.
Let original price be x
Based on the given conditions
45% of x = 50
⇒ 0.45x = 50
⇒ 0.45x = 50
⇒ x = [tex]\frac{50}{0.45}[/tex]
⇒ x = $111.1
Thus, original price of the item is $111.1.

Answer:
The answer is b=128
Step-by-step explanation:
25+27=52
180-52=128
Answer:
∠A + ∠B + ∠C = 180°
⇒ 25° + 27° + ∠B= 180°
⇒ 52° + ∠B= 180°
Subtract both sides by 172°
⇒ 52° – 52° + ∠B = 180° – 52°
Therefore, ∠B = 128°
Which postulate proves these two
triangles are congruent?
A. HL
B. SSA
C. SAS
D. None, not congruent
SAS is the postulate that establishes the congruence of these two triangles.
What is meant by triangle?The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. 180 degrees is the sum of the triangle's three angles. According to the Angle-Side-Angle Postulate (ASA), if two angles from one triangle and its included side are congruent with two angles from another triangle and its included side, then the two triangles are congruent. Three sides and three vertices make up a triangle, which is a polygon. There is a 180 degree angle created inside the triangle. In other words, a triangle's internal angles add up to 180 degrees.To learn more about triangle, refer to:

Daughter’s current age is 6 years which is 1/5 th of her mother’s age. After how many years mother’s age will be three times greater than daughter’s age.
Answer:
6 years
Step-by-step explanation:
6 = ⅕m
m = 30
"mother's age will be three times greater than daughter's age"—Not sure what "three times greater than" means. I will interpret it as: "mother's age will be three times daughter's age."
In x years, mother will be 30+x and the daughter will be 6+x.
30+x = 3(6+x) = 18+3x
12 = 2x
x = 6
In 6 years, the mother will be 36 and the daughter will be 12.
The cost of tuition at a 2 year school is $14,000 per academic year. Todd is eligible for $6,500 in financial aid to cover tuition each year. He will save money for one year to cover the remaining cost of tuition for his two years of school.
What is the minimum amount of money he needs to save each month?
$540
$625
$675
$1,250
Answer:
$625
Step-by-step explanation:
If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:
2(-$14000 + $6500) + 2(12x) = 0.
x is the minimum amount of money he needs to save in order to cover this expense without debt.
Thus 2(-$14000 + $6500) + 2(12x) = 0 →
2(-$7500) + 24x = 0 → -$15000 + 24x = 0 →
24x = $15000 → x = $625
Answer:
$625
Step-by-step explanation:
If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:
2(-$14000 + $6500) + 2(12x) = 0.
