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

Answer:
Diego is moving quickly.
Step-by-step explanation:
Noah and Diego are moving with the constant speed.
But their speeds are different which will be decided by the slope of the lines given in the graph.
Slope of the line representing Noah speed = [tex]\frac{\text{Distance covered}}{\text{Time elapsed}}[/tex]
Since, line for Noah has less slope than line for Diego, speed of Diego will be more.
Therefore, Diego is moving quickly.

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

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]
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

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

what is the surface area???
Answer:
25 m
Step-by-step explanation:
Answer:
[tex]280 {m}^{2} [/tex]
Step-by-step explanation:
Given,
Length of the cuboid = 10m
Breadth of the cuboid = 5m
Height of the cuboid = 6m
Therefore, surface area of the cuboid = 2( lh + lb + bh)
= 2 [(10m × 6m) + (10m × 5m) + (5m × 6m)]
[tex] = 2 \: (60 {m}^{2} + 50 {m}^{2} + 30 {m}^{2} )[/tex]

Jamie says that these terms would simplify to 3ly.
Leslie says the terms would simplify to 7y.
Who do you agree with and why?
Answer:
I agree with Leslie. You must add the first terms to get 19y. then when you add -12y, you subtract 12y from 19y to get 7y.
Step-by-step explanation:
17y + 2y - 12y = 19y - 12y = 7y
Answer: I agree with Leslie. You must add the first two terms to get 19y. Then when you add -12y, you subtract 12y from 19y to get 7y.

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
