a.
A graph has scores on the x-axis, and frequency on the y-axis. A score of 75 has a frequency of 2; 80, 3; 85, 3; 90, 2; 100, 1.
c.
A graph has scores on the x-axis, and frequency on the y-axis. A score of 75 has a frequency of 1; 80, 3; 85, 2; 90, 2; 100, 1.
b.
A graph has scores on the x-axis, and frequency on the y-axis. A score of 75 has a frequency of 2; 80, 3; 85, 2; 90, 2; 100, 1.
d.
A graph has scores on the x-axis, and frequency on the y-axis. A score of 75 has a frequency of 2; 80, 4; 85, 2; 90, 2; 100, 1.

D

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
