Answer:
A student studies the graph shown below and determines that the reflection of point A over the x-axis will result in a point at (6, 3). State whether or not the student is correct, and explain how the correct answer can be found or confirmed.
Step-by-step explanation:
What is the value of y when x = 0? first person to answer I will mark brainiest
Answer:
The point in which the graph crosses the x-axis is called the x-intercept and the point in which the graph crosses the y-axis is called the y-intercept. The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).

Work out the area of a circle with a radius 7.5cm take pie to be 3.142. Give your answer 2 decimal places
Answer:
176.74 cm^2
Step-by-step explanation:
Area of a circle is πr^2
r= 7.5
π= 3.142
Area=3.142× 7.5^2
= 3.142 × 56.25
= 176.74 cm^2
Hence the area if the circle is 176.74cm^2
express 20cm as a percentage of 3m
Answer: [tex]\frac{20}{3} %[/tex]%
Step-by-step explanation:
Convert 3m to cm:
[tex](3m)(\frac{100cm}{1m} )=300cm[/tex]
Now divide 20cm by 300cm:
20cm/300cm=1/15
Multiply (1/15) by 100% to convert the fraction to a decimal:
(1/15)(100%)=[tex]\frac{20}{3} %[/tex]%

In ΔSTU, u = 900 cm, ∠T=49° and ∠U=14°. Find the length of s, to the nearest centimeter.
Answer:
3315
Step-by-step explanation:
delta math
In ΔSTU, u = 900 cm, ∠T=49° and ∠U=14°. Then the length of s is 3425.8 cm
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given,
ΔSTU, u = 900 cm, ∠T=49° and ∠U=14°.
We need to find length of S
From angle sum property the sum of three angles is 180 degrees.
∠S+∠T+∠U=180 degrees
∠S+49°+14°=180°
∠S+63°=180°
∠S=117°
Now use Sine rule
SinU/U=SinS/S
Sin14/900=sin117/S
S=900×Sin 117/sin 14
S=3425.8 cm
Hence, the length of s is 3425.8 cm

write an equivalent expression 3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?
Answer:7c +6d +12
Step-by-step explanation:3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?
3c + 4c +12d - 6d +7 +5
= 7c +6d +12
You combine like terms which are 3c and 4c which gives you 7c .Next you combine 12d and 6d but this time u need to subtract since it has subtact sign in between 12d and 6d which gives you 6d.After that you combine 7 and 5 which u get 12 .Lastly you put all of the tersm together which are 7c and 6d and 12 which get you 7c +6d +12 as your equivalent expression.

The mayor of a town has proposed a plan for the construction of a new community. A political study took a sample of 1300 voters in the town and found that 45% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is more than 42%. Testing at the 0.02 level, is there enough evidence to support the strategist's claim?
Answer:
We reject H₀ , we found enough evidence to support the claim
Step-by-step explanation:
Sample size n = 1300
Sample proportion p = 45 % p = 0,45 and q = 0,55
Proportion of population p₀ = 42 % p₀ = 0,42
Hypothesis Test
Null Hypothesis H₀ p = 0,42
Alternative Hypothesis Hₐ P > 0,42
A one-tail test to the right is needed to evaluate the claim
Sample size big enough to consider binomial distribution can approximate to normal distribution
1300*p > 10 1300*q > 10
Significance level α = 0,02
z(c) fom z-table is z(c) = 2,05
To compute
z(s) = ( p - p₀ ) /√ (p*q)/n
z(s) = ( 0,45 - 0,42 ) /√ (0,45*0,55)1300
z(s) = 0,03 / 0,014
z(s) = 2,14
Comparing z(c) and z(s) z(s) > z(c) then z(s) s in the rejection region we must reject H₀ we found enough evidence to spport the claim

13 squared plus b2 equals 18 squared. What is the answer? Please show the work.
Answer:
Solving [tex](13)^2+(b)^2=(18)^2[/tex] we get [tex]\mathbf{b=\sqrt{155},b=-\sqrt{155}}[/tex]
Step-by-step explanation:
13 squared plus b2 equals 18 squared. What is the answer?
We can write it as:
[tex](13)^2+(b)^2=(18)^2[/tex]
Now, solving and find value of b
We know that 13² = 169
and 18² = 324
Putting values:
[tex](13)^2+(b)^2=(18)^2\\169+b^2=324[/tex]
Subtract 169 on both sides
[tex]169+b^2-169=324-169\\b^2=155[/tex]
Now, taking square root on both sides
[tex]\sqrt{b^2}=\sqrt{155}\\b=\pm\sqrt{155}\\b=\sqrt{155},b=-\sqrt{155}[/tex]
So, solving [tex](13)^2+(b)^2=(18)^2[/tex] we get [tex]\mathbf{b=\sqrt{155},b=-\sqrt{155}}[/tex]
Tina is tossing bean bags at a target. She hit the target on 3 out of her last 15 tries. Considering this data, how many hits would you expect Tina to get during her next 10 tosses?
Answer:
2
Step-by-step explanation:
Because 1 in 5 throws she get 1 in
Answer: We are given 3 out of 15, the best is to convert into a percent, [tex]\frac{3}{15}[/tex] is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.
And your answer is 2 out of 10 tosses.

Suppose that many large samples are taken from a population and that the
sample proportions are normally distributed, with a mean of 0.22 and a
standard deviation of 0.029.99.7% of the sample proportions will fall within
which of the following intervals?
Answer:
99.7% of the sample proportions will fall between 0.133 and 0.307.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 0.22
Standard deviation = 0.029
99.7% of the sample proportions will fall within which of the following intervals?
Within 3 standard deviations of the mean.
Lower end: 0.22 - 3*0.029 = 0.133
Upper end: 0.22 + 3*0.029 = 0.307
99.7% of the sample proportions will fall between 0.133 and 0.307.

Write an equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
(-8, 6)
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is:
y = -4 + 38
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
We have given that,
An equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1
(-8, 6)
What is the slope-intercept form?
y=mx+b
Where m is the slope
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is y = -4 + 38.

Step-by-step explanation:
Given
[tex]Gallons = 4[/tex]
[tex]Weight = 33.4lb[/tex]
Required
Determine the constant of variation (k)
This is calculated by dividing the weight of gallons by the number of gallon.
[tex]k = \frac{Weight}{Gallons}[/tex]
Substitute values for Gallons and Weight
[tex]k = \frac{33.4}{4}[/tex]
[tex]k = 8.35[/tex]
