C. 3x+2=4
Step-by-step explanation:
6x+4=8
Subtract 4 from both sides.
6x=4
Divide both sides by 6
x=4/6
Simplify it
x=2/3
3x+2=4
Subtract both sides by 2
3x=2
Divide both sides by 3
x=2/3
Hope this helps
Answer and Step-by-step explanation:
The correct answer choice is answer choice 3. [ 3x + 2 = 4 ]
6x + 4 = 8
6x = 4
x = 2/3

Two hundred employees from the factory are randomly selected and each is randomly assigued to one of the two techniques. After teaching 100 employees one technique aud 100 employees the other techuique, the manager records the aumber of uaits each of the employees assembles in one week. Which of the following would be the most appropriate inferential statistical test in this situation?
a. Oruc-sauruple z-test
b. Two-sample t-test
c. Matched Pairs t-test
d. Clai-square gooducss-of-fit test
e. One-sample t-test
Answers
Answer:
The most appropriate inferential statistic test in the present situation is the;
b. Two-sample t-test
Step-by-step explanation:
From the question, we have;
The number of subjects in each sample, n₁ = 100
The number of samples = 2
The nature of the test = To compare the two means
The value of the population standard deviation, σ = Unknown
From the given parameters, we have;
The t-test is a method of inferential statistics for determining whether the difference between the mean of two groups is significant, that is if the observed difference are due to chance, where the groups are likely to have some characteristics that are related
The t-test is utilized when testing an hypothesis, and it is used for small samples, where the population standard deviation is unknown
The types of t-test used are;
a) One-sample t-test
b) Two-sample t-test
c) Paired Sample t-test
Therefore, a two-sample t-test is most appropriate.

Given that:
Dividing into 12 steps
Total step, fraction = 1
Each of the 12 steps = 1/12
If two steps is completed in one day:
. Steps completed per day :
2 (1/12)
= 2 /12 steps per day
Fraction of steps completed after 4 days
Fraction of steps per day * number of days
2 /12 * 4

enter the value of P so that the expression 4(10+n) is equivalent to 4(n+p)
Answers
Answer:
I think it is 10
Step-by-step explanation:
Only because I believe n is still unknown and 4 must be multiplied
example
4(10 + n)
40 + 4n
now if P = 10
4(n + p)
4(n + 10)
4n + 40
Answer:
P=10
Step-by-step explanation:
4(10+n)=4(n+p)
40+4n=4n+4p
40=4p+4n-4n
40=4p
p=10

Answer:
45°
Step-by-step explanation:
Sum of angles lying on any part(upper or lower) of a line is 180°.
=> (2x + 45°) + x = 180°
=> 3x = 180° - 45°
=> 3x = 135°
=> x = 135°/3
=> x = 45°
1. A square and a rectangle have the same area. The length of the rectangle is 32
centimeters, and the width of the rectangle is 2 centimeters. What is the length, in
centimeters, of a side of the square?
Answers
Answer:
8
Step-by-step explanation:
A=l*w
32*2=64
A=s*s
s=√A
√64
=8
The length in centimeters of the side of the square is 8 cm.
What is the area of a rectangle and a square?The area of a rectangle and a square are -
A{R} = Length x Breadth
A{S} = Side x Side
Given is that a square and a rectangle have the same area. The length of the rectangle is 32 cm and the width of the rectangle is 2 cm.
It is given that -
A{R} = A{S}
Length x Breadth = Side x Side
32 x 2 = (Side)²
(Side)² = 64
Side = 8
Therefore, the length in centimeters of the side of the square is 8 cm.

9. If AJKL - ANML, find the values of x and y.
Answers
Answer:
x = 35, y = 18
Step-by-step explanation:
Since both triangles are similar, their sides must be proportional with means all of them have a common ratio.
If NM = 16, and KJ = 40. 40/16 is the ratio from ∆NML to ∆JKL. The reciprocal(numerator and denominator flip, the product of a number and it's reciprocal is 1) of this is true from ∆JKL to ∆NML.
Now to find the missing sides you multiply a side by the common ratio to find it's corresponding side length.
Dividing by a number is the same as multiplying by the reciprocal of that number.
40/16 can be reduced to 5/2 or 2 ½ as a mixed fraction.
16/40 can be reduced to 2/5 or 0.4 as a decimal.
Since the scale of ∆JKL is greater than ∆NML, you multiply by 5/2 to get the corresponding side of ∆JKL from ∆NML.
Since the scale of ∆NML is less than ∆JKL, you multiply by 2/5 to get the corresponding side of ∆NNL from ∆JKL.
Therefore x = 14 × 5/2 = 70/2 = 35.
y = 45 × 2/5 = 90/5 = 18.

If the parent graph f(x) = x² is changed to f(x) = 2x², the vertex of the parabola will still remain (0, 0) because whenever the equation of a parabola is in the form y = ax², the vertex will always be (0, 0).
Now if a is a big number, the parabola will become narrower.
So it will stretch vertically and become narrower.
