The first one is 9/16 you have to make 54 and 96 a fraction such as 54/96 then simplify
the second one is 1/5 you have to make 4 and 20 a fraction like this 4/20 then simplify
hope this helps!!
Answer is 2222222222222222222 jk it’s 2
Answer:
19/2 or 9.5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−5)(2)=36
8x+−40=36(Distribute)
8x−40=36
Step 2: Add 40 to both sides.
8x−40+40=36+40
8x=76
Step 3: Divide both sides by 8.
8x/8=76/8
x=19/2

Based on the rules of statistics</span>
68% of the data falls within 1 standard deviation of the mean
95% of the data falls within 2 standard deviation of the mean
99% of the data falls within 3 standard deviation of the mean
20 falls between the range of -56 to 56 (from the given 95%)
Hence we accept the null hypothesis; else, if the mean falls outside the
range, we reject the null hypothesis.

Answer:
72 sq. inch.
Step-by-step explanation:
9 inches in feet is 9/12 = 0.75 feet.
We can set up a ratio to figure out the width of the scale drawing.
This means <u>"if 36 feet is 0.75 feet in drawing, how much (let that be x) is 32 feet?"</u>
<u />
let's cross multiply and solve for x:
<em>So width is 2/3 feet and length is 0.75 feet.</em>
<em>Converting back to inches (since we need the area in sq. inches):</em>
<em>2/3 feet = 2/3 * 12 = 8 inches, and</em>
<em>0.75 feet = 0.75 * 12 = 9 inches</em>
<em />
<em>Hence, area is 8 * 9 = 72 sq. inches.</em>
