Answer:
The population proportion of households that own at least one snow blower is 0.104.
Step-by-step explanation:
In order to find the population proportion of households that own at least one snow blower, you have to divide the number of people that said they owned at least one snow blower by the number of households surveyed:
26/250=0.104
According to this, the answer is that a point estimate for p, the population proportion of households that own at least one snow blower is 0.104.
Using the sample proportion, it is found that the point estimate for p, the population proportion of households that own at least one snow blower, is 0.104.
The sample proportion is given by the number of desired outcomes divided by the number of total outcomes.It is also the point estimate for the population proportion.In this problem:
Sample of 250 households.Of those, 26 owned at least one snow blower.Then:
[tex]p = \frac{26}{250} = 0.104[/tex]
The point estimate is of 0.104.

What is the measure of angle DEA
Answer:
BAC and DAE are two acronyms for BAC and DAE, respectively. Since they are angles at a point, an arc measuring 204 degrees is 360 degrees. BAC is measured at 11 degrees. 5(11)° = 55° is the measure of DAE.

Ciara is making a new dance outfit. She needs 2 ⅓ yards of fabric for the shawl. She needs 1 ¾ years of fabric for the dress. If she has 3 yards of fabric, how much more does she need ?
Answer: 1 1/12 yards
Step-by-step explanation:
Since Ciara needs 2 ⅓ yards of fabric for the shawl and also needs 1 ¾ yards of fabric for the dress, the total yards needed will be:
= 2⅓ + 1¾
= 2 4/12 + 1 9/12
= 3 13/12
= 4 1/12 yards
Since she has 3 yards of fabric, the number of yards needed more will be:
= 4 1/12 - 3
= 1 1/12
Therefore, she needs 1 1/12 yards more.

Which of the following is a solution to the equation y=-1/4x +8 O (10,8) 0 (48) O (49) O (-8.-10)
Answer:
Step-by-step explanation:
The last one -- D -- is the closest correct answer. None of them, however, is right.
y = -1/4 x + 8 Let x = - 8
y = -1/4 * - 8 + 8 The standard rule is starting from the left, do the multiplication first then do the addition
- 1/4 * - 8 will first of all give you a positive result. When 2 minuses are multiplied they give a positive answer.
-1/4 * - 8 = 1/4 * 8
1/4 * 8 = 2
y = 2 + 8
y = 10
So the ordered pair (-8 , 10) is the answer.

One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60
Answer:
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
From the above question, one of the angles = 60°
The value for the two other interior angles = 180° - 60° = 120°
Hence, the following options could be the values of x and y is given as x + y = 120
Therefore,
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60

Triangle BCD is isosceles and BC ≅ BD. Circle A is shown. Isosceles triangle C B D has points on the circle. The lengths of C B and B C are congruent. The measure of arc C D is 100 degrees. What is the measure of Arc B C? 100° 120° 130° 160°
Answer:
130
Step-by-step explanation:
since bc and bd equal the same thing, plug in every answer option until you get to 360.
(130 x 2) = 260
plus cd = 100.
260 + 100 = 360.
The arc length is twice the inscribed angle.
The sum of the three angles must be 180.
The measure of the arc length BC is 130°
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle BCD is isosceles and BC ≅ BD.
Isosceles triangle C B D has points on the circle.
The measure of arc CD is 100 degrees.
This means,
We know that the arc length is twice the inscribed angle.
2 x Angle B = CD
2 x Angle B = 100
Angle B = 100/2
Angle B = 50
Now,
In an isosceles triangle, the angle opposite to the equal sides must be equal.
The sum of the three angles must be 180.
x + x + 50 = 180
2x = 180 - 150
2x = 130
x = 65
Now,
We know that the arc length is twice the inscribed angle.
So,
The measure of the arc length BC.
= 2 x 65
= 130°
Thus,
The measure of the arc length BC is 130°
