Answer: p= 0.644
Step-by-step explanation:
We know that, the confidence interval for population proportion is given by :-
sample proportion(p) ± Margin of error(E)
Given confidence interval : (0.61,0.678)
i.e. p- E = 0.61 ... (i)
p+E = 0.678 ...(ii)
Adding (i) and (ii), we get
2p = 1.288
p= 0.644
From (ii),
E= 0.678-0.644
E= 34
Hence, the value of p = 0.644
Answer:
C
Step-by-step explanation:
The total measurement of a triangle is 180
Triangle 7 has a 40 degree angle and 35 degree angle.
40+35=75
180-75=105
Triangle 8 has the same angle that is 40 degrees and 105. And if you do the same math, you would get 35 for the missing angle of triangle 8
Answer:
The slope is 2/3 and the y intercept is 5/9
Step-by-step explanation:
This is written in the form
y= mx+b where m is the slope and b is the y intercept
y = 2/3x +5/9
m = 2/3 and b=5/9
The slope is 2/3 and the y intercept is 5/9
Answer:
25pi or 78.54
Step-by-step explanation:
The formula for the area of a circle is pi*r^2
We know that r=5ft
A=pi*(5ft)^2
A=25pi ft2
You can write it as 25pi ft2 but you can also write as 25*pi ft2 which is about 78.54 ft2

The Traingle XYZ and ACB are similar triangles. tanX = tanA = 5 over 2 and 5 tenths,
AC = 2 * XY; CB = 2 * YZ
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB, hence XYZ and ACB are similar triangles.
Angles Y and C both measure 90 degrees, and angles A and X are congruent. Hence:
tanX = tanA = 5 over 2 and 5 tenths
AC = 2 * XY; CB = 2 * YZ
