A developer claims that the percent of city residents who favor building a new football stadium is likely between 52.3% and 61.7%.How many residents were surveyed? Round your answer to the nearest whole number
Answer: 453
Step-by-step explanation:
To solve the question, we have to calculate the margin of error which will be:
= (61.7% - 52.3%) / 2
= 9.4% / 2
= 4.7%
4.7% = 1 / ✓n
0.047 = 1 / ✓n
✓n = 1 / 0.047
✓n = 21.28
Square both sides to.gwt the value of n
n = 21.28²
n = 452.69
n = 453
453 residents were surveyed

3)Three times the difference of Federico’s age and 4, increased by 7, is greater than 37. What are possible values of Federico’s age? Graph his possible ages on the number line.
Please help me I need this right away.
Answer:
Federcio's age possible values are those that are greater than 14 i.e 15, 16, 17 and so on
Step-by-step explanation:
Let Federico's age = x
Three times the difference of Federico’s age, and 4 means:
3(x - 4)
Increased by 7:
3(x - 4) + 7
Is greater than 37:
3(x - 4) + 7 > 37
Solving the inequality:
3x - 12 + 7 > 37
3x - 5 > 37
3x > 37 + 5
3x > 42
x > 14
Federcio's age possible values are those that are greater than 14

Geometric mean
Pls help thank u
Answer:
Step-by-step explanation:
1). Geometric mean of a and b = [tex]\sqrt{a\times b}[/tex]
Therefore, geometric mean of 2 and 50 = [tex]\sqrt{2\times 50}[/tex]
= 10
2). By geometric mean theorem,
[tex]\frac{JM}{KM}=\frac{KM}{ML}[/tex]
[tex]\frac{6}{e}=\frac{e}{24}[/tex]
e² = 6 × 24
e = √144
e = 12
Similarly, [tex]\frac{JL}{KJ}=\frac{KJ}{JM}[/tex]
[tex]\frac{6+24}{d}=\frac{d}{6}[/tex]
d² = 6 × 30
d = √180
d = 6√5
And [tex]\frac{JL}{KL}=\frac{KL}{ML}[/tex]
[tex]\frac{6+24}{c}=\frac{c}{24}[/tex]
c² = 30 × 24
c = √720
c = 12√5

HElps What is M∠1 =??
Answer:
m<1 = 145
Step-by-step explanation:
I'm going to name the unkown angle y for clarification
<1 will be x
y + 115 + 30 = 180
y + 145 = 180
y = 35
x + y = 180
x + 35 = 180
x = 145
Answer:
M angle 1 = 145
Step-by-step explanation:
The measurement of angle one is a combination of all the angles present in the triangle. This means that 115+30 is equal to angle 1

is it one solution or many solutions y=2x+7 and y=3x-1
Answer:
the answer is one solution
Answer:
One solution
Step-by-step explanation:
y=2x+7
y=3x-1 (Multiply this by -1)
-y = -3x + 1
y=2x+7
0 = -x + 8
-x = -8
x = 8
y=2x+7
y= 2(8)+7
y = 16 + 7
y = 23

Felix is designing a clock. He sketches the design on a coordinate grid. He graphs the shape of the clock with the vertices (–8, 6), (8, 0), and (8, 6 ). Which statement describes the shape of the clock? The shape has three sides. The shape is a quadrilateral. The shape is a circle. The shape has six sides.
Answer:
A. The shape has three sides
Step-by-step explanation:
Hope this helps, have a great day
The solution is Option A.
The shape of the clock is having three sides and it represents a triangle
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the shape of the clock be represented as A
Now , let the coordinates of the clock be
The first coordinate point of clock P = P ( -8 , 6 )
The second coordinate point of clock Q = Q ( 8 , 0 )
The third coordinate point of clock R = R ( 8 , 6 )
So , there are three sides to the clock with three coordinate points
The figure represents a triangle with 3 sides
Therefore , the value of A is a triangle
Hence , the figure represents a triangle

If T is the centroid of ∡MNP, TN = 16, MQ = 23, and RP = 18, find each missing measure.
a) QT = ______
b) QN = ______
c) QP = ______
d) MP = ______
e) RT = _______
f) TP = ________
Answer:
a) QT = 8
b) QN = 24
c) QP = 23
d) MP = 46
e) RT = 6
f) TP = 12
Step-by-step explanation:
Find the diagram attached
If T is the centroid of<MNP, then the following are true;
TN = 2QT
Given TN = 16
16 = 2QT
QT = 16/2
QT = 8
QN = QT + TN
QN = 8 + 16
QN = 24
MQ + QP = MP and MQ = QP
If MQ = 23
QP = 23
Recall that MP = MQ + QP
MP = MQ + MQ
MP = 2MQ
MP = 2(23)
MP = 46
Similarly, TP = 2RT
RT = TP/2
Also RP = RT + TP
RP = RT + 2 RT
RP = 3RT
18 = 3RT
RT = 18/3
RT = 6
Recall that TP = 2RT
TP = 2(6)
TP = 12

75% of salmon pass through a single dam unharmed. By what percent does the number of salmon decrease when passing through a single dam?
Answer:
100%-75%= 25%
...........
The percentage that represents the number of salmon decrease when passing through a single dam will be 25%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
75% of salmon pass through a single dam unharmed.
The percent that represents the number of salmon decrease when passing through a single dam will be given as,
⇒ 100% - 75%
⇒ 25%
The percentage that represents the number of salmon decrease when passing through a single dam will be 25%.

Write the equation of the line shown on the graph in slope-intercept form.
Remember Slope-Intercept Form is y=mx+b
Answer:
[tex]y = x -3[/tex]
Step-by-step explanation:
1) First, find the slope by using the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. We can see that the two points marked on the line are (0, -3) and (3,0). So, substitute the x and y values of those points into the formula and solve:
[tex]m = \frac{(0)-(-3)}{(3)-(0)} \\m = \frac{0+3}{3-0} \\m = \frac{3}{3} \\m=1[/tex]
So, the slope is 1.
2) Slope-intercept form is represented by the formula [tex]y = mx+b[/tex]. Substitute values for [tex]m[/tex] and [tex]b[/tex] in order to write an equation.
Substitute 1 for [tex]m[/tex] since it represents the slope. Substitute -3 for [tex]b[/tex] since it represents the y-intercept. (Remember that the y-intercept is the point at which the line intersects the y-axis. So, by looking at the graph provided, we can see that (0,-3) is the y-intercept without doing any calculations.) This gives the following answer:
[tex]y = x -3[/tex]
