Answer:
Your answer is in the Step by Step
Step-by-step explanation:
4=32x
We move all terms to the left:
4-(32x)=0
We move all terms containing x to the left, all other terms to the right
-32x=-4 x=-4/-32 x=1/8
Answer:
the answer is x=1/8
in the decimal form, it's x=0.125
Step-by-step explanation:
isolate the variable by dividing each side by a factor that doesn't contain the variable
hope this helps.

Find angle a (use info in pic)
The botanist would like to estimate the average weight of mustard seeds grown in a certain type of soil; weight of the seeds is known to follow a normal distribution. The botanist collects a random sample of 10 mustard seeds and finds that the sample average and sample standard deviation are 528 mg and 49 mg respectively. Select from the following the correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data.
a. (480.1, 539.9)
b. (525.2, 534.8)
c. (479.4, 540.6)
d. (473.6, 546.4)
e. The necessary assumptions have not been satisfied and the calculation cannot be performed.
f. (469.4, 550.6)
Answer:
The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
T interval
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.833
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.833\frac{49}{\sqrt{10}} = 28.4[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 528 - 28.4 = 499.6 mg
The upper end of the interval is the sample mean added to M. So it is 528 + 28.4 = 556.4 mg
The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).

9y = 13y2 - 4
The discriminant of the quadratic is ?
Answer:
289
Step-by-step explanation:
1. if to re-write the given equation, then 13y²-9y-4=0;
2. if to calculate the required discriminant, then:
D=81+13*4*4=208+81=289.
Answer:
289
Step-by-step explanation:
[tex]13y^2-9y-4 = 0\\[/tex]
D = [tex]b^2-4ac[/tex]
Wherein,
b = 9
a = 13
c = -4
[tex]D = 9^2-(4*13*-4)\\= 289[/tex]
Which equation represents a line which is perpendicular to the line 4x+3y=-24
Step-by-step explanation:
we know that slope of the line is
[tex] - \frac{4}{3} [/tex]
if the line is perpendicular to the other line, the product
of the slope is -1
so the answer is -4x+3y=-24 or
4x-3y=-24
you also can change the 24 to others number because it will not influences the slope.
suppose that an individual has a body fat percentage of 19.8% and weighs 162 pounds. How many pounds of his weight is made up of fat? Round your answer to the nearest tenths
Answer:
32.1 pounds
Step-by-step explanation:
Given data
Percentage of body fat= 19.8%
Weight= 162pounds
Let us find 19.8% of the persons weight
=19.8/100*162
=0.198*162
=32.076
Therefore, 32.1 pounds of the weight is fat

Which of the given functions could this graph represent?
OA. f(t) = (x - 1)(x - 2)(x + 1)(x + 2)
O B. f(x) = x(x - 1)(1 + 1)
Oc. /(x) = x(x - 1)(x - 2)(x + 1)(x + 2)
OD. (r) = x(x - 1)(x - 2)
Two linear functions are shown. Which function has the greater initial value?
Answer:
Function A has the greater initial value because the initial value for Function A is 6 and the initial value for Function B is 3.
Step-by-step explanation:
✔️Function A:
Initial value = y-intercept (b)
y-intercept is the value of y, when the corresponding value of x = 0
From the table, y = 6 when x = 0.
The y-intercept of function A = 6
Therefore, initial value for Function A = 6
✔️Function B:
y = 4x + 3 is given in the slope-intercept form, y = mx + b.
b = y-intercept = initial value.
Therefore
Initial value for Function B = 3
✔️Function A has the greater initial value because the initial value for Function A is 6 and the initial value for Function B is 3.

Factor: 2x + 2y
Show work please
Answer:
2(x + y)
Step-by-step explanation:
You can pull out a 2 from the expression.
So divide 2x by 2 and 2y by 2.
2x/2 = x
2y/2 = y
2(x + y)
Quadrilateral A'B'C'D'is the result of rotating quadrilateral ABCD by 60° about the origin.
Choose all answers that apply
a. BC and B'C' are both parallel to the y-axis
b. <B and <B' have the same measures
c. D and D' have the same coordinates
d. none of the above
Answer:
a. No
b. Yes
c. No
Step-by-step explanation:
a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.
b. When you rotate a figure none of the angles in the figure change.
c. For D and D' to have the same coordinates the figure must be rotated by 360.
