Step-by-step explanation:
The histogram shows the sizes (in acres) of 44 vineyards.
<u>a. Approximately what percentage of these vineyards are at or over 210 acres? </u>
10+13 = 23 of the vineyards are at or over 210 acres. Total is 44, so
- 23/44*100% = 52% rounded to the nearest percent
<u>b. Describe the distribution (shape, center, spread, unusual features). </u>
- A. The distribution is uniform.
- <u>B. The distribution is bimodal. </u>
- C. The distribution is unimodal.
<u>Is the distribution symmetric or skewed? </u>
- <u>A. The distribution is skewed to the left. </u>
- B. The distribution is symmetric.
- C. The distribution is skewed to the right.
<u>Which of the following best describes the center? </u>
- A. The center is best described by the mean since the distribution is symmetric and there are no outliers.
- B. The center is best described by the median since the distribution is skewed to the right and has an outlier.
- <u>C. The center is best described by the median since the distribution is skewed to the left and has an outlier. </u>
<u>What is the spread?</u>
- The acreage ranges from 30 to 270 acres.
- 30, 90, 120, 210, 240, 270
<u>Describe any unusual features. </u>
- A. There are no unusual features.
- B. Most of the vineyards have close to the same number of acres.
- <u>C. There is one vineyard that has considerably fewer acres, 0 to 30 acres, than the rest.</u>
The area is 28 and the perimeter is 14
And the explanation is Area= Length x Width and Perimeter= Length + length + width + width
Answer:
149 feet
Step-by-step explanation:
you have a quadratic equation and you need to fid it's vertex because that is the max height
h(t)= -16t² +96t +5
the x coordinate of the vertex is x= -b/2a for f(x)= ax²+bx+c so in our case
x= = 3 , now we know that the vertex bbelongs to the graph so should verify the equation so we substitute t of the value of x=3 to find y
y= -16*3²+96*3+5= -144+288+5=149
the max height is the coordinate of y because it tels us how much it went up
The correct answer is c
4x - y = 3d
add y to both sides
4x = 3d + y
divide both sides by4
x = 3d+y/4
The measure of m∠3 =20°
Step-by-step explanation:
Given that:
m∠1 = (3x-5)° and m∠2= (2x+15)° then
∠ABE= m∠1= opposite vertical angles are equal
∠ABE =∠BEF = alternate angles
m∠2= ∠BEF = opposite vertical angles are equal
Thus m∠1 = m∠2
(3x-5)° = (2x+15)°
3x-5=2x+15
3x-2x=15+5
x=20°
m∠2 and m∠3 are opposite angles in the parallelogram DEHG which are congruent thus m∠3 =20°
