-46 − 8x > 22.
A. x -8.5 D. x > 8.5
Answer:
x < -8.5
Step-by-step explanation:
-46 - 8x > 22
-8x > 68 -- when you divide by a negative number in an inequality, you flip the inequality sign
Therefore, x < -8.5

Priya has 50 identical parcels. Each parcel has a mass of 17 kg, correct to the nearest kilogram. Find the upper bound for the total mass of the 50 parcels.
Answer:
The upper bound for the total mass of the 50 parcels is 850 kilograms.
Step-by-step explanation:
From statement we infer that upper bound is represented by the 50 identical parcels completely full. Then, the upper bound is the product of number parcels and maximum capacity of each parcel:
[tex]m_{UP} = (50\,parcel)\cdot \left(17\,\frac{kg}{parcel} \right)[/tex]
[tex]m_{UP} = 850\,kg[/tex]
The upper bound for the total mass of the 50 parcels is 850 kilograms.
A real estate sales agent receives a salary of $250 per week plus a commission of 2% of sales.
a. Identify the Slope m _________
b. Identify the initial value b ________________
c. Write an equation that gives the weekly income y in terms of sales x ______________.
d. What is his weekly income if the sales were $600.00?
Answer:
a. The slope m is 0.02
b. The initial value b is 250
c. y = 0.02x + 250
d. His weekly income is $262 if the sales were $600.00
Step-by-step explanation:
the form of the linear equation is y = m x + b, where
m is the slope (rate of change)b is the y-intercept (constant amount)∵ A real estate sales agent receives a salary of $250 per week
→ This is a fixed amount every week
∴ b = 250
∵ They give a commission of 2% of sales
→ This value depends on the sales (rate of change)
∵ 2% = 2 ÷ 100 = 0.02
∴ m = 0.02
a. The slope m is 0.02
b. The initial value b is 250
∵ y represents the weekly income
∵ x represents the sales
∵ m = 0.02 and b = 250
∴ The equation is y = 0.02x + 250
c. y = 0.02x + 250
∵ The sales were $600.00
∴ x = 600
→ Substitute it in the equation to find y
∵ y = 0.02(600) + 250
∴ y = 12 + 250
∴ y = 262
d. His weekly income is $262 if the sales were $600.00

Step-by-step explanation:
A selective university advertises that 96% of its bachelor’s degree graduates have, on graduation day, a professional job offer or acceptance in a graduate degree program in their major area of study. In a sample of 227 recent graduates this was true of 209 of them. The probability of obtaining a sample proportion as low as or lower than this, if the university’s claim is true, is about:________
a. 0.015
b. 0.001
c. 0.131
d, 0.084
Answer:
The probability is [tex]P( p < 0.9207) = 0.0012556[/tex]
Step-by-step explanation:
From the question we are told
The population proportion is [tex]p = 0.96[/tex]
The sample size is [tex]n = 227[/tex]
The number of graduate who had job is k = 209
Generally given that the sample size is large enough (i.e n > 30) then the mean of this sampling distribution is
[tex]\mu_x = p = 0.96[/tex]
Generally the standard deviation of this sampling distribution is
[tex]\sigma = \sqrt{\frac{p (1 - p )}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.96 (1 - 0.96 )}{227} }[/tex]
=> [tex]\sigma = 0.0130[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{209}{227}[/tex]
=> [tex]\^ p = 0.9207[/tex]
Generally probability of obtaining a sample proportion as low as or lower than this, if the university’s claim is true, is mathematically represented as
[tex]P( p < 0.9207) = P( \frac{\^ p - p }{\sigma } < \frac{0.9207 - 0.96}{0.0130 } )[/tex]
[tex]\frac{\^ p - p}{\sigma } = Z (The \ standardized \ value\ of \ \^ p )[/tex]
[tex]P( p < 0.9207) = P(Z< -3.022 )[/tex]
From the z table the area under the normal curve to the left corresponding to -3.022 is
[tex]P(Z< -3.022 ) = 0.0012556[/tex]
=> [tex]P( p < 0.9207) = 0.0012556[/tex]
Vector Calculus
A particle of mass m move along the path σ(t)={t^2,sin t, cos t} Calculate the force acting on the particle t=0.
It seems like σ(t) is the positive function of the particle. Compute its acceleration by differentiating this function twice.
σ(t) = {t ², sin(t ), cos(t )}
σ'(t) = {2t, cos(t ), -sin(t )}
σ''(t) = {2, -sin(t ), -cos(t )}
When t = 0, the acceleration on the particle is
σ'' (0) = {2, -sin(0), -cos(0)} = {2, 0, -1}
Then the force acting on the particle at time t = 0 is
F = {2m, 0, -m}
by Newton's second law.
If the mean of 50 scores is exactly 26,4, and the mean of 49 of those scores is exactly 26, is the 50 score ?
Answer:
The 50th score is 46.
Step-by-step explanation:
Given that
[tex]a_{50} = 26.4\\a_{49} = 26\\n_1 = 50\\n_2 = 49[/tex]
In order to find the 50th score we have to find sum of 49 values and 50 values and then subtract them.
Average is given by the formula:
[tex]Average = \frac{Sum}{Number\ of\ values}\\[/tex]
Using this formula, we can calculate sum for both averages
So,
[tex]a_{50} = \frac{s_{50}}{n_1}\\26.4 = \frac{s_{50}}{50}\\26.4*50 = s_{50}\\s_{50} = 1320[/tex]
And
[tex]a_{49} = \frac{s_{49}}{n_2}\\26.4 = \frac{s_{49}}{49}\\26*49 = s_{49}\\s_{49} = 1274[/tex]
Now for the 50th score,
[tex]50th\ score = s_{50} - s_{49} = 1320-1274 = 46[/tex]
Hence,
The 50th score is 46.

Martin and Sue are collecting clothes for a clothing drive. Sue collected 1/5 as many clothes as Martin did. If Martin collected 2 1/2 bags of clothes, how many bags of clothes did Sue collect?
Answer:
Sue collected 1/2 bags of clothes.
Step-by-step explanation:
Fractions
Let's solve the problem from end to beginning.
Martin collected 2 1/2 bags of clothes for a clothing drive. This mixed fraction can be expressed as:
[tex]2\frac{1}{2}= 2+\frac{1}{2}=\frac{5}{2}[/tex]
Sue collected 1/5 as many clothes as Martin did. This means she collected:
[tex]\frac{1}{5}\cdot \frac{5}{2}[/tex]
Multiplying:
[tex]\frac{1}{5}\cdot \frac{5}{2}=\frac{1}{2}[/tex]
Sue collected 1/2 bags of clothes.

2.
[tex](4h)^2 + 36[/tex]
[tex](4*3)^2 + 36[/tex]
[tex](12)^2 + 36[/tex]
[tex]144 + 36[/tex]
[tex]180[/tex]
Hence:
[tex](4h)^2 + 36=180[/tex]
3.
[tex]4h^2 + 24[/tex]
[tex]4*3^2 + 24[/tex]
[tex]4 * 9 + 24[/tex]
[tex]36 + 24[/tex]
[tex]60[/tex]
Hence:
[tex]4h^2 + 24 = 60[/tex]

Which inequality can be used to represent this problem? A company spent $15,000 developing a new graffiti repelling paint. The company makes $10 on the sale of each gallon of paint after subtracting manufacturing costs. How many gallons, x, will they need to sell to have a profit of at least $50,000?
A 10x — 15000 ≥ 50000
B 10x — 15000 > 50000
C 10x + 50000 > 15000
D 10x + 50000 ≥ 15000
Answer:
The correct answer is:
Option A: A 10x — 15000 ≥ 50000
Step-by-step explanation:
Given that the total cost of manufacturing by the company is $15000.
Let x be the number of gallons the company sells.
It is also mentioned that the company earns $10 on each gallon.
So the total profit will be the the difference of the selling cost of gallons and manufacturing cost
Mathematically,
[tex]10x-15000[/tex]
Now it is mentioned that the profit should be at least 50000 dollars which means the profit can be minimally 50000 and also can be greater than it so
[tex]10x-15000 \geq 50000[/tex]
The number of gallons can be found by solving the obtained inequality.
Hence,
The correct answer is:
Option A: A 10x — 15000 ≥ 50000
