Answer:
Step-by-step explanation:
In both the point, y-coordinates are same. So, the line is parallel to x-axis
Slope of the line parallel to x-axis =0
m = 0
Equation : y =6.7
Make a proportion.
⇒
=
Solve for x to find the weight of the elephant on planet B. Cross multiply; (100)(x) and (3)(2200).
You now have:
100x = 6600.
Divide both sides by 100.
x = 66
The elephant would weigh
66 pounds on planet B.

Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is
Answer:
1.26
Step-by-step explanation:
Given that:
For ACT:
Mean score, m = 19.3
Standard deviation, s = 5.3
Zscore for ACT score of 26;
Using the Zscore formula :
(x - mean) / standard deviation
x = 26
Zscore :
(26 - 19.3) / 5.3
= 6.7 / 5.3
= 1.2641509
= 1.26
Answer:
50.05 cm^2
Step-by-step explanation:
Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.
The rectangle's size is 6.5x5.5=35.75 cm^2
The rectangle's size is 11.7-6.5 to get the base length, which is 5.2
The height is 5.5
So it's 5.2*5.5/2=14.3 cm^2
14.3+35.75=50.05 cm^2
Answer:
For a. divide 125 by 300 then multiply by 100
The answer for a. is 41.66%
For b. convert percentage to decimal divide by 100 then multiply 0.15 by 2.25 to get 0.3375. Round it off to 0.34 and subtract that from 2.25 to get
The answer for b. is $1.91
For c. you have to figure out the difference first. 2.50 minus 2.00 is 0.50
So then what percent of 2.00 is 0.50
Divide 2.00 by 0.50 to get 4.
The answer for c. is 4%
Honestly this was kinda rushed because I'm in the middle of a quiz so yea hope this helps you.
