solve the equation below for x
cx - 4 = 7
A. x = 11/c
B. x = c/11
C. x = c/e
D. x = 3/c
Answer:
x = 11/c
Step-by-step explanation:
cx - 4 = 7
Add 4 to each side
cx - 4+4 = 7+4
cx = 11
Divide each side by c
cx/c = 11/c
x = 11/c

What is the sum of 4/10x + -1x + 1 7/10x?
Answer:
I think its 11x/10
Step-by-step explanation:
It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handed desks to place in the big lecture halls being constructed on its campus. In a random sample of 290 students from that college, whether or not a student was left-handed was recorded for each student. The college wants to know if the data provide enough evidence to show that students at this college have a different percentage of left-handers than the general American population? State the random variable, population parameter, and hypotheses. State the Type I and Type II errors in the context of this problem.
Step-by-step explanation:
The random variable (x) here would be a randomly selected student from the college that is left-handed.The population parameter would be 11% of America's total population. The total population as of 2019 is believed to be 328.2 million, and 11% of that figure is about 36.1 million (thirty-six million one hundred thousand).Hypotheses: Remember, the null hypothesis usually reflects the held view of the researcher, and since we are told the college wants to know if the data provide enough evidence to show that students at this college have a different percentage of left-handers than the general American population. It could read; There is a statistically significant difference in the percentage of left-handers in the college than the American population. While the alternate hypothesis could read; There is no statistically significant difference in the percentage of left-handers in the college than the American population.The Type I error implies rejecting the null hypothesis when it is actually true. That is: Rejecting that the % of all students from that college that are left-handed is 11 % when the % is really 11 %.The Type II error implies accepting the null hypothesis when it is actually false. That is: Failing to reject that the % of all students from that college that are left-handed is 11 % when the % is actually different.You drop a seashell into the ocean from a height of 40 feet. Write an equation that models the height h in feet) of the seashell above the water after seconds. How long is the seashell in the air? Round your answer to the nearest tenth.
Answer:
t=1.58 seconds
Explanation:
The equation which models the height h of the seashell above water after t seconds
Height of seashell above water after t seconds; h = 40 - 8t²
Time that seashell is in air; t = 1.58 s
The sea shell is dropped under gravity and thus, from Newton's equations of motion, we know that height/distance is;
S = ut + ½gt²
Since it was dropped from a height and not the ground, then;
h = height of shell from ground
h_o = height from which the shell was dropped.
Thus, we have;
h - h_o = ut + ½gt²
We are told that the seashell was dropped into the ocean from a height of 40 ft. Thus;
h_o = 40 ft
It was dropped from rest and so; u = 0 ft/s
Acceleration due to gravity is; g = -32ft/s² (since it is free fall)
Thus;
h - 40 = 0(t) + ½(-32t²)
h = 40 - 8t²
The time that the seashell in the air will be after it has hit the surface which will be when h = 0.
Thus;
0 = 40 - 16t²
16t² = 40
t² = 40/16
t² = 2.5
t = √2.5
t = 1.58 s

Thank you!!
Answer:
360=297+(x-36)+25
360=297+25-36+x
360=286+x
360-286=x
74=x
Answer:
x = 74 degree
Step-by-step explanation:
All those angles must add up to 360 degrees:
360 degrees = (297 + x - 36 + 25) deg, or
360 = 297 - 36 + 25 + x, or
x = 74 degrees

rico bought 3.4 pounds of coffee that cost $6.95 per pound how much did he spend on coffee?
estimate: 18-28, 22-38, 36-50, or 8-18
solution: ??
Answer:
$23.63
Step-by-step explanation:
Your just adding decimals if I understood the question. So basically you just multiply 6.95 by 3 which gets you 20.85.
And then you divide 6.95 by 10 which is .695, and then multiply that by 4 which gets you to 2.78.
So now you just add those two up
20.85 + 2.78 = 23.63
Your welcome :)

Jason went to his local zoo that featured 38 reptile exhibits. If these reptile exhibits make up 95% of the zoo's exhibits, then how .any exhibits does the zoo have in total
Answer:
40 exhibits
Step-by-step explanation:
First, we will what we have gotten into fractions.
There are 38 reptile exhibits, but we dont know how much exhibits there is total, so we will make the total x: 38/x
We know that a percent is out of 100, so our fraction for the percent is 95/100
Now we are going to cross multiply 38/x and 95/100
38 * 100 = 3800
x * 95 = 95x, so 3800 = 95x
Divide both sides by 95 and you get 40.

In a certain Algebra 2 class of 28 students, 9 of them play basketball and 17 of them
play baseball. There are 6 students who play neither sport. What is the probability
that a student chosen randomly from the class plays both basketball and baseball?
Answer: Probability of a student playing both basketball and baseball is 4/28 or 14.3%
Step-by-step explanation:
1) Students playing atleast one sport = 28 - 6 = 22
2) N(Basketball ∩ Baseball) = N(Basketball) + N(Baseball) - N (Basketball U Baseball)
N(Basketball ∩ Baseball) = 9 + 17 - 22 = 4
3) Number of students playing both basketball and baseball = 4
Total number of students = 28
Probability of a student playing both basketball and baseball is 4/28
4/28= 0.1428571429 x 100%= 14.3%
Answer:4/28
Step-by-step explanation:4/28
Line segment AB is shown on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment AB is shown with A as ordered pair 1, 3 and B as ordered pair 5, 3. The line segment is rotated 270 degrees counterclockwise about the origin to form A′B′. Which statement describes A′B′? (5 points) A′B′ is parallel to AB. A′B′ is half the length of AB. A′B′ and AB are equal in length. A′B′ is greater than twice the length of AB.
Answer:
A′B′ and AB are equal in length.
Step-by-step explanation:
Given that the location of the points are at A(1, 3) and B(5, 3).
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Rigid transformation are transformation that preserves the shape and size when performed. Types of rigid transformation are reflection, rotation, translation.
Hence if AB is rotated 270 degrees counterclockwise about the origin to form A′B′, both A′B′ and AB are equal in length because rotation is a rigid transformation.
If A(x,y) is rotated 270 degrees counterclockwise about the origin, it becomes A'(y,-x).
Hence if AB is rotated 270 degrees counterclockwise about the origin to form A'(3, -1), B'(3, -5)
[tex]AB=\sqrt{(5-1)^2+(3-3)^2} =4\\\\A'B'=\sqrt{(3-3)^2+(-5-(-1))^2}=4,[/tex]
