A function is defined by y = 2x + 1. What is the range of the function if the domain is {0, 2, 3}?
{0, 4, 6}
{0, 4, 6}
{1, 5, 7}
{1, 5, 7}
{0, 2, 3}
{0, 2, 3}
{2, 4, 5}
{2, 4, 5}
9514 1404 393
Answer:
{1, 5, 7}
Step-by-step explanation:
For x=0, y = 2·0 +1 = 1
For x=2, y = 2·2 +1 = 5
For x=3, y = 2·3 +1 = 7
The range is the list of y-values, so is {1, 5, 7}.

You want to buy a trampoline. You found one online that has a circumference of 6.28 yards. What is the area?
Please show work thank you so much!!! 30 points
Work Shown:
C = 2*pi*r
6.28 = 2*3.14*r
6.28 = 6.28r
6.28r = 6.28
r = (6.28)/(6.28)
r = 1
The radius of the circle is 1 yard.
A = pi*r^2
A = 3.14*1^2
A = 3.14
The area is roughly 3.14 square yards.
The area of the trampoline is mathematically given as
a = 3.14
What is the area?Question Parameters:
You found one online that has a circumference of 6.28 yards
Generally, the equation for the Circumference is mathematically given as
C = 2*pi*r
Thererfore
6.28 = 2*3.14*r
r = (6.28)/(6.28)
r = 1
In conclusion, where radius is
[tex]a= pi*r^2[/tex]
a = 3.14*1^2
a = 3.14

Answer:
See below.
Step-by-step explanation:
a) √2 + √50 + √98
= √2 + 5√2 + 7√2
= 13√2
c) 5√7 + 2√5 - 3√28
= 5√7 + 2√5 - 6√7

A random sample of 200 shoppers at a local grocery store found that 135 of the 200 sampled
would be willing to use self-checkout kiosks if the store installed them (ộ = 0.675).
Assuming you believe the initial results to be reasonable, how many samples would be required if
you wanted to re-do the sample, construct a 95% confidence interval, and reduce the margin of
error to 3%?
Round your answer to the nearest whole number. Remember: with sample sizes we always round
up!
Using the z-distribution, as we are working with a proportion, it is found that samples of 937 should be taken.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this problem, we have that:
The estimate is of [tex]\pi = 0.675[/tex].The margin of error is of M = 0.03.95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].Then, we solve for n to find the minimum sample size.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.675(0.325)}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.675(0.325)}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.675(0.325)}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.675(0.325)}}{0.03}\right)^2[/tex]
[tex]n = 936.4[/tex]
Rounding up, it is found that samples of 937 should be taken.

[tex]x = 2 \sqrt{2} i \: or \: x = - 2 \sqrt{2} i[/tex]
Step-by-step explanation:
• Add 7 to both sides.
[tex]3x {}^{2} - 7 + 7 = - 31 + 7[/tex]
• Simplify
[tex]3x {}^{2} = - 24[/tex]
• Divide both sides by 3

at the movies, la quinta paid for drinks and popcorn for herself and her two children. she spend twice as much on popcorn as on drinks. if her total bill came to $17.94, how much did she spend on drinks and how much did she spend on popcorn?
Answer:
Step-by-step explanation:
let the amount spent on popcorn be x and amount spent on drinks be y
If the total bill paid is $17.94, then x+y = $17.94
If she spend twice as much on popcorn as on drinks, then y = 2x
Substitute y = 2x into the original equation
x+y = $17.94
x + 2x = $17.94
3x = $17.94
x = $17.94/3
x = $5.98
Since y = 2x
y = 2($5.98)
y = $11.96
Therefore she spent $5.98 on popcorn and $11.96 on drinks

[tex]\\ \rm\Rrightarrow 12x-6=90[/tex]
[tex]\\ \rm\Rrightarrow 12x=96[/tex]
[tex]\\ \rm\Rrightarrow x=8[/tex]
Answer:
x = 8
Step-by-step explanation:
Complementary angles are two angles with measures that sum to 90°
Given:
m∠C = (5x)° m∠D = (7x − 6)°⇒ m∠C + m∠D = 90°
⇒ 5x + 7x - 6 = 90
⇒ 12x - 6 = 90
⇒ 12x = 96
⇒ x = 8
Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
3.9
Step-by-step explanation:
The right triangle is marked with the sides adjacent and opposite the angle. That suggests the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(52°) = 5/x
x = 5/tan(52°) ≈ 3.9
the measure of angle sqr is 65 the measure of angle pqs is x what is the vaule of x
Answer:
40
Step-by-step explanation:
The value of a right angle is 90° and <SQR is a fraction of <PQR.
Hence, <PQS, which is the other fraction of <PQR, equals 90-50 and 90-50 is 40.
Or we can do it like this;
⇒ 180-90-50
⇒ 90 - 50
⇒ 40
Thus, Answer is 40.

QS =
Answer:
The volume of a prism is given by ...
V = Bh
Step-by-step explanation:
Here, the base is an equilateral triangle with side length 3 in. The area of such a triangle is given by
A = (√3)4*s²
where s is the side length.
Your triangular prism has a base area of ...
B = (√3)/4*(3 in)² = (9/4)√3 in²
so the volume is
V = ((9/4)√3 in²)(6 in)
V = (27/2)√3 in³
V ≈ 23.383 in³

Answer: D) The linear model shows a strong fit to the data
The actual strength of the relationship is unknown unless we have the actual values of each data point (so we can compute the correlation coefficient r), but the residuals are randomly scattered about both above and below the horizontal axis. This means we have a fairly good linear fit. If all of the points were above the line, or all below the line, or all residuals fit a certain pattern (eg: parabola), then it wouldn't be a good linear fit.

you ride your bike at an average of 12 miles per hour on the way to school, and at an average of 15 miles per hour on the way home. The total ride time is 22 minutes. How far away is school? Round your answer to the nearest hundredth of a mile
Answer: 2.44 miles.
Step-by-step explanation:Answer:
2.44 miles
Step-by-step explanation:
Give the following :
Average miles to school = 12 miles per hour
Average Miles from school = 15 miles per hour
Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667
Recall:
Speed = distance / Time
Time = distance / speed
Let distance = d
For the scenario described :
d/12 + d/15 = 0.3667
(5d + 4d) / 60 = 0.3667
5d + 4d = 22
9d = 22
d = 22/9
d = 2.44 miles
