Answer:
The correct option is: The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Step-by-step explanation:
We have given a table. According to that table a survey about the amount of time students spend doing homework each week has been conducted. The students were either in college or in high school. Now which of the choices below best describes how to measure the spread of this data.
The correct option is: The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answer:
17
Step-by-step explanation:
Using the law of cosines in ΔABC
b² = a² + c² - (2ac cosB) ← substitute in values
= 25² + 28² - (2 × 25 × 28 × cos36.9°)
= 625 + 784 - 1400 cos36.9°
= 1409 - 1400 cos36.9° ( Take the square root of both sides )
b = ≈ 17 ( nearest whole number )
The peaches cost more per pound because if you divide the pounds of peaches by the cost, it's more than the cost per pound of apples.
Step-by-step explanation:
let width be "w"
given,length of rectangle is 3 units greater than its width
length= w+ 3
perimeter of rectangle= 2( l+ b)
= 2[( w+3)+ w]
= 2(w to the power of 2 + 3w)
= 2w to the power of 2 + 6w
is the answer
