Answers
Answer:
Infinite number of solutions
Step-by-step explanation:
The two expressions are actually equal to each other. When two functions are equal to each other, they will have infinite number of solutions.
Answer:
infinite number of solutions
Step-by-step explanation:
-10m - 3 = -3 - 10m
add 3 to each side
-10m = -10m
any value substituted in for 'm' will make the equation true

Calculate the measures of spread for Mrs. Hampton’s class data. Justify your response by describing the process used to find each measure. (2 points)
Answers
Answer:
The measures of spread for Mrs. Hampton’s class data come in a few different ways. One is the IQ range, the IQ Range is the Lower Quartile and Upper Quartile subtracted. The IQR is 8-5 = 3.
Hope this helps! Have a nice day! <3

The measure of spread for the data in Mrs. Hampton’s class when using the interquartile range is 3.
What is a measure of spread?It should be noted that the measure of spread simply describes how similar or varied the set of observed values are for a variable.
The measures of spread include the quartiles, range, interquartile range, variance, and standard deviation.
In this case, the interquartile range will be the difference between the lower quartile and the upper quartile. This will be:
= 8 - 5 = 3

would say yes if you asked 430?
Answers
Answer:
129 people would say yes if you asked 430 people
Step-by-step explanation:
430 ÷ 20 = 21.5
6 × 21.5 = 129
129/430 = 0.3
6/20 = 0.3
This means they are equivalent and 129 people would say yes

Answers
I know the 1st one.
Answer:
(x+3)(x-4) = x-12
Step-by-step explanation:
This is called a foil method
1st: We multiply the two first numbers - x*x = 2x
2nd: We multiply the two outside numbers - x*(-4) = -4x
3rd: We multiply the two inside numbers - 3*x = 3x
4th: We multiply the two last numbers - 3*(-4) = -12
Then we combine them - 2x-4x+3x-12
Then we simplify - x-12

A farmer plans to grow wheat and corn. Each acre of wheat requires 4 hours of labor and $20 of capital, and each acre of corn requires 16 hours of labor and $40 of capital. The farmer has at most 800 hours of labor and $2400 of capital available. If the profit from an acre of wheat is $80 and from an acre of corn is $100, how many acres of each crop should she plant to maximize her profit?
Answers
Answer:
To maximize profits, the farmer should plant 120 acres of wheat, and no acre of corn.
Step-by-step explanation:
Given that a farmer plans to grow wheat and corn, and each acre of wheat requires 4 hours of labor and $ 20 of capital, and each acre of corn requires 16 hours of labor and $ 40 of capital, and the farmer has at most 800 hours of labor and $ 2400 of capital available, if the profit from an acre of wheat is $ 80 and from an acre of corn is $ 100, to determine how many acres of each crop should she plant to maximize her profit the following calculation must be performed:
Knowing that each acre of wheat has a 50% lower capital cost, 75% lower hours and a 20% lower profit, in principle this would be the crop to be planted to obtain better yields.
2400/20 = 120
120 x 4 = 480
120 x 80 = 9,600
Thus, to maximize profits, the farmer should plant 120 acres of wheat, and no acre of corn.

A cell phone company is proposing to offer a discount to seniors if there was evidence that their average call length was less than the overall population mean of 9.2 minutes. If the phone calls are too long and the discount is provided, the company will lose money. A random sample of the length of calls for 100 randomly selected seniors was determined.
(a) State the null and alternative hypotheses. Write 's' as '<=', '' as '>=', and '#' as '<>'.
(b) In context, explain what the Type I error is.
(c) In context, explain what the Type II error is.
(d) Which is worse for the seniors, a Type I error or a Type II error? Why?
Answers
Step-by-step explanation:
1. Null hypothesis:
h0: μ ≥ 9.2
alternative hypothesis
h1: μ < 9.2
2. the type 1 error is an error that occurs when we reject a true null hypothesis. in this question, the type 1 error is commited if we reject the null hypothesis that the population mean is greater than or equal to 9.2, then we have committed this error.
3. the type ll error is an error that o a false occures wehn we do not reject a false null hypothesis. We commit the type ll error in this scenario by saying that the population mean is greater than or less than 9.2 when it is actually false.
4. The type ii eror is actually worse here. we accept a false H0 in the type ii error which says that the mean is greater than or equal to 9.2. This means that these seniors are not going to get discount because they only get discount when their mean calls is less than 9.2 minutes.
someone help me with this question plzzz
Answers
Answer:
Step-by-step explanation:
As per Janayda,
From the figure attached,
In ΔTRQ,
m∠TRQ + m∠RQT + m∠QTR = 180°
25° + m∠RQT + 35° = 180°
m∠RQT = 180° - 60°
m∠RQT = 120°
Since, m∠RQT + m∠PQT = 180° [Linear pair of angles]
m∠PQT = 180° - m∠RQT
= 180° - 120°
= 60°
In right angled triangle TPQ,
m∠TPQ + m∠PQT + m∠PTQ = 180°
90° + 60° + m∠PTQ = 180°
m∠PTQ = 180° - 150°
= 30°
Similarly, other angles can also be evaluated from the given information.
In ΔQTP and ΔNTP,
TP ≅ TP [Reflexive property]
NP ≅ PQ [Given]
ΔQTP ≅ ΔNTP [By LL postulate for congruence]
Therefore, Janayda is correct.
While Sirr is incorrect.
Since, there is not the enough information to prove ΔRTQ and ΔMTN equal, Isabelle is incorrect.

Determine the vertex of the function f(x)=2(x+1)(x+7). You must show all algebraic steps for full marks
Answers
Answer:
vertex (-4,-18)
Step-by-step explanation:
f(x)=2(x+1)(x+7)
f(x)=2(x^2+8x+7)
f(x)=2x^2+16x+14
f(x)=2(x^2+8x)+14
f(x)=2(x^2+8x+4^2-4^2)+14
f(x)=2(x^2+8x+4^2)+2(-4^2)+14
f(x)=2(x^2+8x+4^2)+2(-4^2)+14
f(x)=2(x^2+8x+4^2)-18

There were 48 blue, 48 green, and 48 yellow crayons. Also there were 72 red crayons and 120 colored pictures. What is the largest number of identical sets can be made of these crayons and pictures?
Answers
Answer:
24
Step-by-step explanation:
For this problem, you need to find the greatest common factor because you need to divide all of the materials equally into identical sets.
If you factor out the numbers 48, 72, and 120, (same # of blue, green, and yellow crayons) you'll get the GCF of 24.
48 - 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
72 - 1, 2, 3, 4, 18, 6, 8, 9, 12, 24, 36, 72
120 - 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
The greatest common factor in all of these lists is 24.
Therefore, the largest number of identical sets is 24.

Jennifer has been saving for college for 57 months. The first month, she saved $11. She was able to save more money each month than the month before. She ended up saving $19,779.00. How much more did she save each month?
(A) $11.00
(B) $11.50
(C) $12.00
(D) $12.50
Step-by-step explanation:
his is an arithmetic sequence with first term (a) = 11, number of terms (n) = 57, sum of nth term (Sn) = 19,779.
Let the amount of money she saved more each month be d, then
Sn = n/2(2a + (n - 1)d)
19,779 = 57/2(2(11) + (57 - 1)d)
19,779 = 28.5(22 + 56d)
19,779 = 627 + 1,596d
19,779 - 627 = 1,596d
d = 19,152/1,596 = 12
Therefore, she saved $12.00 more each month.
