x is greater than or equal -3 and less than 5
use x only once in your inequality
Answer:
-3 <= x < 5
Step-by-step explanation:
Because x is less than 5, we put a less than sign. And x is greater than or equal to -3, so we have to put that specific sign.
Which expressions are equivalent ( 0.2) 3 x ( 0.3 ) 4?
Hey there!
Assuming you meant….
(0.2)^3 * (0.3)^4
= 0.2^3 * 0.3^4
= 0.2 * 0.2 * 0.2 * 0.3 * 0.3 * 0.3 * 0.3
= 0.04 * 0.2 * 0.09 * 0.09
= 0.008 * 0.0081
= 0.0000648
≈ 0.000065
Therefore, your answer should be:
0.0000648

54. Given that P is a positive number, N is a negative
number, and | P | > | N |, which of the following
expressions has the greatest value?
Answer: Choice G [tex]\left| \frac{p-n}{n} \right|[/tex]
============================================================
Explanation:
Pick a positive number for p, and a negative value for n. Make sure that p is further away from 0 than n is (so that [tex]|p| > |n|[/tex] is a true statement).
I'll go for these values
p = 5n = -2Replace every copy of p with 5, and replace every copy of n with -2. Then evaluate or simplify. Use your calculator if needed.
Let's start with choice F.
[tex]F = \left| \frac{p-n}{p} \right|\\\\F = \left| \frac{5-(-2)}{5} \right|\\\\F = \left| \frac{5+2}{5} \right|\\\\F = \left| \frac{7}{5} \right|\\\\F = \left| 1.4 \right|\\\\F = 1.4\\\\[/tex]
Now onto choice G
[tex]G = \left| \frac{p-n}{n} \right|\\\\G = \left| \frac{5-(-2)}{-2} \right|\\\\G = \left| \frac{5+2}{-2} \right|\\\\G = \left| \frac{7}{-2} \right|\\\\G = \left| -3.5 \right|\\\\G = 3.5\\\\[/tex]
Next up is evaluating the expression for choice H.
[tex]H = \left| \frac{p+n}{p-n} \right|\\\\H = \left| \frac{5+(-2)}{5-(-2)} \right|\\\\H = \left| \frac{5-2}{5+2} \right|\\\\H = \left| \frac{3}{7} \right|\\\\H \approx \left| 0.4286\right|\\\\H \approx 0.4286\\\\[/tex]
Then let's compute expression J.
[tex]J = \left| \frac{p+n}{p} \right|\\\\J = \left| \frac{5+(-2)}{5} \right|\\\\J = \left| \frac{5-2}{5} \right|\\\\J = \left| \frac{3}{5} \right|\\\\J = \left| 0.6 \right|\\\\J = 0.6\\\\[/tex]
Lastly, compute expression K.
[tex]K = \left| \frac{p+n}{n} \right|\\\\K = \left| \frac{5+(-2)}{-2} \right|\\\\K = \left| \frac{5-2}{-2} \right|\\\\K = \left| \frac{3}{-2} \right|\\\\K = \left| -1.5 \right|\\\\K = 1.5\\\\[/tex]
-----------------------------------
To summarize, when plugging p = 5 and n = -2 into each expression, we got these results:
F = 1.4G = 3.5H = 0.4286 (approximate)J = 0.6K = 1.5Expression G leads to the largest output.
Therefore, [tex]\left| \frac{p-n}{n} \right|[/tex] has the largest value when p > 0 and n < 0.
The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, p is a positive number, n is a negative number, and |p| > |n|.
Let us consider p=5 and n=-2
Now,
F) |(p-n)/p|
= |(5-(-2))/5|
= |7/5|
= 1.4
G) |(p-n)/n|
= |(5-(-2))/(-2)|
= |7/(-2)|
= 3.5
H) |(p+n)/(p-n)|
= |(5-2)/(5-(-2))|
= |3/7|
= 0.43
J) |(p+n)/p|
= |(5-2)/5|
= |3/5|
= 0.6
K) |(p+n)/n|
= |(5-2)/2|
= |3/2|
= 1.5
The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.

The margin error is 2.82%.
What is Margin of Error?A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample
The margin of error for a sample proportion is given by
[tex]z_{\alpha /2}\sqrt{ \frac{p(1-p)}{n} }[/tex]
where p is the sample proportion and n is the sample size.
Consider the confidence level of 95%, then [tex]z_{\alpha /2}[/tex] = 1.96
p = 53% = 0.53 and n =1200
Thus, Margin of error=
[tex]z_{\alpha /2}\sqrt{ \frac{p(1-p)}{n} }[/tex]
=1.96[tex]\sqrt{ \frac{0.53(1-0.53)}{1200} }[/tex]
=1.96*0.0144
=0.0282

Michael has saved $40. He got a summer job mowing lawns, and gets $9 for every lawn he mows. How many lawns does Michael need to mow to save exactly $121, the cost of a concert ticket?
Answer:
9
Step-by-step explanation:
9 × 9 = 81
81 + 40 = 121
121 is the amount of money you want so you just have to mow 9 lawns to get your exact amount of money you need.
I need this pls!! I forgot my notes :(
Answer:
D
Step-by-step explanation:
when x = 0, y = 40
therefore you can pick either A or D only.
while x increases, y decreases, that's negative relation
so, answer is D
Answer:
Option D
Step-by-step explanation:
y = mx + b
b is the y - intercept (when x = 0):
this graph doesn't show any negative values on the axis so options B and C can't be true since it they have - 40 when its positive 40
y = mx + 40
The dot association is going downwards, the y values are getting smaller
making this a negative association leaving on ly option d true
z^2 + 11z+ 28 find the factor of polynomial
Answer:
(z+7)*(z+4)
Step-by-step explanation:
The first term is, z2 its coefficient is 1 .
The middle term is, +11z its coefficient is 11 .
The last term, "the constant", is +28
Step-1 : Multiply the coefficient of the first term by the constant 1 • 28 = 28
Step-2 : Find two factors of 28 whose sum equals the coefficient of the middle term, which is 11 .
-28 + -1 = -29
-14 + -2 = -16
-7 + -4 = -11
-4 + -7 = -11
-2 + -14 = -16
-1 + -28 = -29
1 + 28 = 29
2 + 14 = 16
4 + 7 = 11 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 4 and 7
z2 + 4z + 7z + 28
Step-4 : Add up the first 2 terms, pulling out like factors :
z • (z+4)
Add up the last 2 terms, pulling out common factors :
7 • (z+4)
Step-5 : Add up the four terms of step 4 :
(z+7) • (z+4)
Which is the desired factorization

1.Mary has ( 20xy - 10x²) sweets. She wants to divide the sweets equally among her (5x) friends.
if X=6 and Y=4, how many sweets:
how many friends does Mary have?
Answer:
Mary has 120 sweets and 30 friend.Step-by-step explanation:
if x = 6 and y = 4
then
20xy - 10x² = 20×(6)×(4)-10×(6^2) = 120
Therefore,
Mary has 120 sweets
……………………………………
if x = 6 and y = 4

Answer:
x = 37DG = 22AG = 44AD = 66Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Thus, AD = AG +GD = 44 +22 = 66

What is algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Pete is making decorations for a dinner party. The instructions tell him to use 9 flowers for a medium-sized decoration which has 2 lilies, 1 rose, 3 carnations, 2 daffodils and 1 iris.
The ratio of daffodils to total flower is,
n=2/9.
To make a large decoration, Pete uses 36 flowers. Let suppose the daffodils flower he needs for this is x. Thus,
x=36*(2/9)
x=4*2
x=8
The rose flower is increased from 1 to 2. Thus, the total number of flower also be twice for decoration.
Flower=2*9
Flower=18
Now Pete uses 10 lilies instead of 2 which is 5 times the medium-sized decoration. Thus, the carnations to be needed is,
Carnations=3*5
Carnations=15
Hence, the daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

Consider the following statistic. as of january 2009, the usa has produced 60,000 metric tons of nuclear waste in 60 years of operating 104 nuclear power plants. on average, how much waste is produced by each plant on a monthly basis? 0.8 tons per month 83.3 tons per month 104 tons per month 866.3 tons per month
Using proportions, it is found that the average waste produced by each plant on a monthly basis is of 0.8 tons per month.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there is a period of 60 x 12 = 720 months, with 104 plants, and 60,000 tons of waste were produced, hence the average is given by:
A = 60000/(720 x 104) = 0.8 tons per month.

Step-by-step explanation:
If 21 people study French and everyone studies some language, then the other 4 people must be Spanish only students. 25 - 21 =4
Since 13 people study Spanish,
13-4=9
9 people must study both Fr and Sp.
If 9 people study BOTH, then
21-9=12,
12 people must be the Fr only people.
The arch-looking, upsidedownU is intersect.
Fr intersect Sp are the StudyBOTH people.
P(Both) = Both/Total
= 9/25
If you need %, divide 9÷25 and times by 100. That's 36%
F' means Not French people, which is Spanish only people (thankfully there are no No-Language-studiers bc they would count too)
P(F')
= P (not Fr)
= P (Sp Only)
= 4/25 = 16%
