Solve the following equation using elimination method
Step-by-step explanation:
Let's solve your system by elimination.
3k−4m=−1;2k+3m=12
Multiply the first equation by 3,and multiply the second equation by 4.
3(3k−4m=−1)
4(2k+3m=12)
Becomes:
9k−12m=−3
8k+12m=48
Add these equations to eliminate m:
17k=45
Then solve17k=45for k:
17k=45

Answer:
d = -10
Step-by-step explanation:
Hey there!
Let's Solve:
2d - 9 = -29 => Step 1: Add 9 to both sides(becasue we are subtracting 9)2d = -20 =>Step 2: Divide both sides by 2(because we are multiplying by 2 in 2d)d = -10-Chetan K
A tree grows at the rate of 1½ inches every week. At this rate, how many weeks will it take the tree to grow 20.25 inches?
(1) The scores ou an aptitude test for finger dexterity are uonually distributed with meau 250 and
standard deviation 65.
a) What is the probability that a person selected at random will score between 240 and 270 on the
test?
b) Test is given to a random sample of seven people. What is the probability that the mean score,
I for the sample will be between 240 and 270?
Using the normal distribution and the central limit theorem, it is found that there is a:
a) 0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.
b) 0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is of [tex]\mu = 250[/tex].The standard deviation is of [tex]\sigma = 65[/tex].Item a:
The probability is the p-value of Z when X = 270 subtracted by the p-value of Z when X = 240, hence:
X = 270:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{270 - 250}{65}[/tex]
[tex]Z = 0.31[/tex]
[tex]Z = 0.31[/tex] has a p-value of 0.6217.
X = 240:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{240 - 250}{65}[/tex]
[tex]Z = -0.15[/tex]
[tex]Z = -0.15[/tex] has a p-value of 0.4404.
0.6217 - 0.4404 = 0.1813.
0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.
Item b:
We have a sample of 7, hence:
[tex]n = 7, s = \frac{65}{\sqrt{7}} = 24.57[/tex]
X = 270:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{270 - 250}{24.57}[/tex]
[tex]Z = 0.81[/tex]
[tex]Z = 0.81[/tex] has a p-value of 0.7910.
X = 240:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{240 - 250}{24.57}[/tex]
[tex]Z = -0.41[/tex]
[tex]Z = -0.41[/tex] has a p-value of 0.3409.
0.7910 - 0.3409 = 0.4501.
0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.

75% of the students are boys. There are 24 boys. What is the total number of students?
Answer: 32
Step-by-step explanation:
We can write the problem like this:
[tex]\frac{75}{100}x=24[/tex]
Then, we can multiply 100 to the equation:
[tex]75x=2400[/tex]
Now, we can divide 2400 and 75:
[tex]x=32[/tex]
Now we can conclude that the amount of students is 32.
How do you determine an end behavior of a logarithmic graph?
The end behavior of the parent function is consistent.
As x approaches infinity, the y-values slowly get larger, approaching infinity. As x approaches 0 from the right (denoted as x → 0+), the y-values approach negative infinity.

A rectangle is drawn so that the width is 2 feet shorter than the length. The area of the rectangle is 48 square feet. Find the length of the rectangle.
Given :
Rectangle is drawn so that the width is 2 feet shorter than the length.The area of the rectangle is 48 sq feet.⠀
To Find :
The Length of the rectangle⠀
Solution :
We know that,
[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\: [/tex]
So,
Let's assume the width of the rectangle as x and the length will be (x + 2).
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \sf \: { \dashrightarrow (x + 2) \times x = 48 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x = 48 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x - 48 = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} +8x -6x- 48 = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x} (x +8) -6(x+8) = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow (x +8) (x - 6) = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow x = -8, \: \: x = 6 }[/tex]
⠀
Since, The width can't be negative, so the width will be 6 which is positive.
⠀

numbers divisible by 2 end with an even number (2,4,6,8,0)
numbers divisible by 5 end with either 5 or 0
Answer:
A,D, and F
Step-by-step explanation:
Any number that is even is divisible by 2.
A D and F are even numbers. If a number ends in 2,4,6,8, or 0 then it is an even number, so you can just look at the last number and determine weather it is divisible by 2.

9 bags sorry for the other answer
she has 7 boxes at home, then she goes and buys 6 more from the store, now she has 7 + 6 = 13 boxes of chips, each box of chip has 13 bags, so the total amount of potato chips I guess is 13 * 13 = 169 bags total.
So she split it even among her 9 students, so how many times does 9 go into 169? 169 ÷ 9, has a quotient of 18 with a remainder of 7.
18 * 9 = 162, plus 7 = 169, which is the total amount of potato chips bags.

Use the graph to solve the system of equations.
Answer:
( -2 , 1 )
Step-by-step explanation:
Add the 2 equations downwards.
( -x+4y=6 ) + ( 2x-y=-5 )...consider the sign of each term.
= x + 3y = 1
Put -2 in x because that's where the graph above shows an intersection of the 2 equations.
-2 + 3y = 1
3y = 3
y = 1.
