Joe wrote an inequality
for each of the following
statements. Decide whether
Joe's written inequality is
TRUE or FALSE based on
what's typed and compare it
to what he actually wrote.
A
The sum of a number and 7 is not more than 10
x + 7 < 10
B
The product of a number and 4 is at least 20
4X > 20
C
The difference between a 15 and a number is at most 12
15-x>12
D
The quotient of a number and 8 is greater than or equal to
8x <3
Answer:Please see answer in explanation column
Step-by-step explanation:
A
The sum of a number and 7 is not more than 10
Given answer: x + 7 < 10 , This is false
Reason :Not more than 10 means at most 10, less than or equal to 10 , " or " not greater than 10 "and therefore the correct inequality is written as
x + 7 ≤ 10
B
The product of a number and 4 is at least 20
Given answer: 4X > 20 ---- False
Reason :At least 20 means at no less than 20 " or " greater than or equal to 20 therefore the correct inequality is written as
4X ≥ 20
C
The difference between a 15 and a number is at most 12
Given answer: 15-x>12----False
Reason :At most 12 means " no more than 12 , " " less than or equal to 12 , " or " not greater than 12"therefore the correct inequality is written as
15-x ≤ 12
D
The quotient of a number and 8 is greater than or equal to
Given answer 8x <3 --False
Reason : It clearly stated greater than or equal to 3. Therefore the correct inequality is 8x ≥ 3

Answer:
c=66°
Step-by-step explanation:
a=51°
51+63=114°
180-114°= 66°
Answer:
66
Step-by-step explanation:
a° = 51° (corresponding angles)
a = 51
a° + c° + 63° = 180° (interior angle sum postulate of a triangle)
51° + c° + 63° = 180°
c° + 114° = 180°
c° = 180° - 114°
c° = 66°
c = 66

What is the point-slope equation of a line with slope -4 that contains the point
(-2,7)?
A. Y+7 = -4(x-2)
B. y-7 = -4(x - 2)
c. y+ 7 = -4(x + 2)
D. Y-7 = -4(x + 2)
Answer:
y -7 = -4(x + 2) (Answer D)
Step-by-step explanation:
The general point-slope equation is y - k = m(x - h)
If the slope, m, is -4, and the point is (h, k) with h = -2 and k = 7), then we have in this case
y -7 = -4(x + 2) (Answer D)

What is answer too 12a over 2
Answer:
6a
Step-by-step explanation:
A researcher claims that 45% of U.S. adults think that the IRS is not aggressive enough in pursuing people who cheat on their taxes. You believe the true percentage is more than 45%. To test this, you take a simple random sample of 500 U.S. adults and find that 245 of them say the IRS is not aggressive enough.
Required:
a. What's the minimum population size required?
c. How many successes were there?
c. Test at 0.01 significance.
I’m just tryna get up my bag yurt
Answer:
a) Then minimum sample size is n = 12
b) We got 245 successes
c)p-value is greater than 0,01 Therefore we accept H₀.
We can´t support our claim
Step-by-step explanation:
a) The minimum population size required to use the approximation of binomial distribution to normal distribution can be obtained from:
n*p > 5 p = 0,45 0,45 * n > 5 n > 11
Then minimum sample size is n = 12
b) We got 245 successes out of n = 500
x = 245 p = 245/500 p = 0,49
q = 1 - p q = 1 - 0,49 q = 0,51
Test Hypothesis:
Null Hypothesis H₀ p = 0,45
Alternative Hypothesis Hₐ p > 0,45
Alternative Hypothesis indicates that the test is a one tail test to the right
z( s) = ( p - 0,45 ) / √ p*q/n
z( s) = ( 0,49 - 0,45 ) / √ 0,49*0,51 / 500
z( s) = 0,04 / 0,0223
z(s) = 1,793
p- value for z = 1.79 is from z-table p-value = 0,0367
Comparing p-value with the significance level 0,01 we see that
p-value is greater than 0,01 Therefore we accept H₀.
We can´t support our claim

Answer:
26.2 in³
Step-by-step explanation:
The formula for the volume of a cone uses the radius of the cone as one of its variables. Here, the diameter is given, so we need to divide it by 2 to find the radius.
r = d/2 = (5 in)/2 = 2.5 in
The volume is ...
V = 1/3πr²h
V = (1/3)π(2.5 in)²(4 in) = 25π/3 in³ ≈ 26.2 in³
The volume of the cone is about 26.2 in³.

Find the missing side. Round to
the nearest tenth.
10
33°
х
x = [ ?
]
Answer:
x = 15.4
Step-by-step explanation:
Reference angle = 33°
Opposite side reference angle = 10
Adjacent side = x
Therefore, we would apply the trigonometric function, TOA.
Thus:
Tan 33° = Opposite/Adjacent
Tan 33° = 10/x
Multiply both sides by x
x*Tan 33° = 10
Divide both sides by Tan 33°
x = 10/Tan 33°
x = 15.3986496
x = 15.4 (nearest tenth)
write the first five terms of the sequence.. NO LINKS!!!
Answer:
5,50,500,5000,50000
Step-by-step explanation:
The first term is given
a1 =5
The second term is when n=2
a2 = 10 * a1 = 10 * 5 = 50
The third term is when n=3
a3 = 10 * a2 = 10 * 50 = 500
The fourth term is when n=4
a4 = 10 * a3 = 10 * 500 = 5000
The fifth term is when n=5
a5 = 10 * a4 = 10 * 5000 = 50000

Linda bought a total of 12 lb of flounder and shrimp and paid $20 for the flounder and $20 for the shrimp. If the price per pound of the shrimp is twice that of the flounder, how many pounds of each did she buy?
Select one:
a.
8 lb shrimp and 4 lb flounder
b.
4 lb shrimp and 8 lb flounder
c.
6 lb shrimp and 6 lb flounder
d.
2 lb shrimp and 10 lb flounder
Answer:
B: 4 lb shrimp and 8 lb flounder
Step-by-step explanation:
if the price of shrimp is twice the price for flounder, you will have twice as much flounder as you have shrimp, so in terms the only answer that applies to this is B.
Customers enter the waiting line at a cafeteria on a first-come, first served basis. The arrival rate follows a Poisson distribution, and service times follow an exponential distribution. If the average number of arrivals is 6 per minute and the average service rate of a single server is 10 per minute. What is the average number of customers in the system?
Answer:
the average no of customers in the system is 0.9
Step-by-step explanation:
Given that
The average number of arrivals is 6 per minute
And, the average service rate of a single server is 10 minutes
We need to find out the average no of customers in the system
So,
Lq = rho^2 / 1 ÷ rho
= (6 ÷ 10)^2 ÷ (1 - 6 ÷ 10)
= 36 ÷ 100 × 10 ÷ 4
= 0.9
Hence, the average no of customers in the system is 0.9

Work out the cost of 12kg of potatoes and 1 1/2kg of carrots
Answer:
The cost is #15.90
Step-by-step explanation:
See comment for complete question
Given
[tex]P \to Potato[/tex]
[tex]C \to Carrot[/tex]
[tex]3P + 2C = 5.08[/tex]
[tex]P = 1.24[/tex]
Required
[tex]12P + 1\frac{1}{2}C = ??[/tex]
First, we solve for C
Substitute [tex]P = 1.24[/tex] in [tex]3P + 2C = 5.08[/tex]
[tex]3 * 1.24 + 2C = 5.08[/tex]
[tex]3.72 + 2C = 5.08[/tex]
Collect like terms
[tex]2C = 5.08 - 3.72[/tex]
[tex]2C = 1.36[/tex]
Solve for C
[tex]C = \frac{1.36}{2}[/tex]
[tex]C = 0.68[/tex]
So, we have:
[tex]P = 1.24[/tex]
[tex]C = 0.68[/tex]
[tex]12P + 1\frac{1}{2}C = ??[/tex] becomes
[tex]12P + 1\frac{1}{2}C = 12*1.24 + 1\frac{1}{2}*0.68[/tex]
[tex]12P + 1\frac{1}{2}C = 14.88 + 1.02[/tex]
[tex]12P + 1\frac{1}{2}C = 15.90[/tex]
Carlos has chosen 12 different CDs he would like to buy: 4 are rap music, 5 are country, and 3 are heavy metal. He has only enough money to buy 5 of them (each CD costs the same price). So he selects 5 of them at random. What is the probability that his purchase includes at least one CD from each of the three genres.
Answer:
The probability is 0.7449
Step-by-step explanation:
Given
[tex]n = 12[/tex] ---- total
[tex]r = 5[/tex] --- selection
[tex]Genre =\{Rap(4), Country (5), Heavy\ metal (3)\}[/tex]
Required
Probability of buying at least 1 of each genre
First, we calculate the total possible selection.
To select 5 CDs from a total of 12, we use:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
[tex]^{12}C_5 = \frac{12!}{(12 - 5)!5!}[/tex]
[tex]^{12}C_5 = \frac{12!}{7!5!}[/tex]
Expand
[tex]^{12}C_5 = \frac{12*11*10*9*8*7!}{7!*5*4*3*2*1}[/tex]
[tex]^{12}C_5 = \frac{12*11*10*9*8}{5*4*3*2*1}[/tex]
[tex]^{12}C_5 = \frac{95040}{120}[/tex]
[tex]^{12}C_5 = 792[/tex]
So, the total selection is:
[tex]Total = 792[/tex]
To select at least 1 from each genre, there are 6 possible scenarios.
And they are:
[tex]\begin{array}{ccc}{Heavy\ Metal (3)} & {Rap (4)} & {Country(5)} & {3} & {1} & {1} & 2 & {1} & {2} & {2} & {2} & {1}& {1} & {2} & {2}& {1} & {3} & {1}& {1} & {1} & {3} \ \end{array}[/tex]
The possible selections for the given scenario is:
[tex]Possible = ^3C_3* ^4C_1 * ^5C_1 +^3C_2* ^4C_1 * ^5C_2 +^3C_2* ^4C_2 * ^5C_1 +^3C_1* ^4C_2 * ^5C_2 +^3C_1* ^4C_3 * ^5C_1 +^3C_1* ^4C_1 * ^5C_3[/tex]
Using a calculator, we have:
[tex]Possible = 1*4*5 +3*4*10 +3*6*5 +3*6*10+3*4*5+3*4*10[/tex]
[tex]Possible= 20 +120 +90 +180+60+120[/tex]
[tex]Possible = 590[/tex]
The probability is then calculated using:
[tex]Pr = \frac{Possible}{Total}[/tex]
[tex]Pr = \frac{590}{792}[/tex]
[tex]Pr = 0.7449[/tex]
