Find the numbers missing from this table of data that gives a prediction of
how many students are freshmen, sophomores, juniors, and seniors based on
data found in a sample of 1000 students:
Answer:
a = 21%
b = 260%
c = 25%
Step-by-step explanation:
I just answered that question
In Stacia's town, 60% of registered people vote
regularly. A spinner with equal-sized sections
numbered 0 to 9 can be used to represent those
who do and
do not vote.
a. What numbers can be assigned to represent
those who do vote and those who do not vote?
Answer:
6 Voted , 4 Not Voted
Step-by-step explanation:
10 sections, so 0.60 * 10 = 6 sections Voted
0.40 * 10 = 4 sections not Voted
Determine the volume of the rectangular prism. (3 points)
30/7 cm2
1/3cm
Answer:
10/7 cm^3
Step-by-step explanation:
I can only assume that '30/7 cm^2' represents the area of the base and 1/3 cm the height. If and only if that is the case, then the volume is
V = (base area)(height) = (30/7 cm^2)(1/3 cm) = 10/7 cm^3.
anyone know how to do this?
Answer: A reasonable estimate of the minimum is 20.
Which is equivalent to √3+√12?
Answer:
3[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying [tex]\sqrt{12}[/tex]
[tex]\sqrt{12}[/tex]
= [tex]\sqrt{4(3)}[/tex]
= [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex]
= 2[tex]\sqrt{3}[/tex]
Then
[tex]\sqrt{3}[/tex] + [tex]\sqrt{12}[/tex]
= [tex]\sqrt{3}[/tex] + 2[tex]\sqrt{3}[/tex]
= 3[tex]\sqrt{3}[/tex]

Can someone please help me out with this question please I beg you no links
can someone please help its my last one
Answer:
80 + 40 + (x + 64) = 180
120 + (x + 64) = 180
-120 -120
x + 64 = 60
-64 -64
X = -4
Step-by-step explanation:
Let's double check
64 - 4 = 60
60 + 80 + 40 = 180 It works!
Therefore X = -4.

What is "y" when x = -2 in the equation y = 2x + 5
Answer:
2 x -2 + 5
-4 + 5
1 = y
Step-by-step explanation:
Plug in the value of X and do the equation.
Answer:
y = 1
Step-by-step explanation:
When x = -2 :
y = 2x + 5
y = 2(-2) + 5
y = -4 + 5
y = 1

Solve for x. The figure is a parallelogram
Answer:
x = 1
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, then
94x + 1 = 95 ( subtract 1 from both sides )
94x = 94 ( divide both sides by 94 )
x = 1
Someone PLEASEEEE HELPPPP
Answer:
x = 18√3
Step-by-step explanation:
From the picture attached,
In a right triangle,
Measure of one angle = 30°
Measure of adjacent side of the angle = 9 units
We have to find the measure of Hypotenuse from the given properties.
By cosine rule,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3}}{2} =\frac{9}{x}[/tex]
[tex]x=18\sqrt{3}[/tex]
Therefore, measure of Hypotenuse is 18√3 units.

Which best describes the function represented by the data in the table? linear with a common ratio of 2 linear with a common first difference of 2 quadratic with a common ratio of 2 quadratic with a common first difference of 2
Answer:
linear with a common first difference of 2
Step-by-step explanation:
If this is linear, the common first difference, or slope, will be the same throughout the entire table.
The formula for slope is

For the first set of points, we have:
m=(0--2)/(-2--3) = (0+2)/(-2+3) = 2/1 = 2
For the second set of points, we have:
m = (4-0)/(0--2) = 4/(0+2) = 4/2 = 2
For the third set of points, we have:
m = (12-4)/(4-0) = 8/4 = 2
The rate of change, or slope, is constant; this makes the function a linear function with a common first difference of 2

Solve (find x intercepts) using the quadratic formula
f(x)= -5x^+9x-4
Answer:
[tex]x[/tex]-intercepts at [tex](1,0)[/tex] and [tex](0.8,0)[/tex]
Step-by-step explanation:
A quadratic in the form [tex]ax^2+bx+c=y[/tex] crosses the [tex]x[/tex]-axis when [tex]y=0[/tex].
The first step is replacing [tex]f(x)[/tex] with [tex]y[/tex].
So: [tex]y= -5x^2+9x-4[/tex]. With the information above, we can find the [tex]x[/tex] intercepts by setting [tex]y = 0[/tex].
Therefore [tex]0=-5x^2+9x-4[/tex].
Now we can use the quadratic formula because it is in the form [tex]ax^2+bx+c=0[/tex].
Note the quadratic formula: [tex]\frac{-b\frac{+}{-}\sqrt{b^2-4ac} }{2a } = x[/tex].
To find the values of [tex]a[/tex],[tex]b[/tex] and [tex]c[/tex] we can compare the equation to the general equation.
Therefore: [tex]a=-5[/tex], [tex]b=9[/tex] and [tex]c=-4[/tex].
Now put these values into the quadratic formula:
[tex]\frac{-9\frac{+}{-}\sqrt{(9)^2-4(-5)(-4)} }{2(-5) } = x[/tex]
And simplify:
[tex]\frac{-9\frac{+}{-}\sqrt{81-80} }{-10 }[/tex] , [tex]\frac{-9\frac{+}{-}\sqrt{1} }{-10 }[/tex].
[tex]\sqrt{1} =1[/tex], therefore [tex]x = \frac{-9\frac{+}{-}1 }{-10 }[/tex]
Now we can have two values for [tex]x[/tex]. One when we take away the discriminant ([tex]b^2-4ac[/tex]) and one when we add it.
So [tex]x = \frac{-10}{-10} = 1[/tex]
or
[tex]x = \frac{-8}{-10} = 0.8[/tex]
Therefore [tex]x[/tex]-intercepts at [tex](1,0)[/tex] and [tex](0.8,0)[/tex]

Describe the steps you can use to graph the function y=2x^2-8
Answer:
The first thing you need to find is the axis of symmetry by using
-b/2a
after you find that, use it to find the vertex of
x
2
+
8
In this case x should equal
0
so
y
=
0
2
+
8
giving just 8
the y-intercept is 8 as
c
=
8
the graph should look like this
graph{x^2+8 [-11.5, 8.5, 0.84, 10.84]}
it is a parabola.

Step-by-step explanation:
The experimental probability is the probability that is determined on the basis of the results of an experiment repeated many times. Since Vernon tossed 8 heads during his 20 experiments, the experimental probability of tossing heads is [tex]\frac{8}{20}[/tex] or [tex]\frac{2}{5}[/tex].
