Answer:
-1.53 , 1.53
Step-by-step explanation:
It is basically asking you to find the percentiles. so for the bottom 6.3% you would type into your calculator 2nd, VARS, invNorm, area: .063, mean: 0, and Standard Deviation: 1 which gives you -1.53.
for the upper 6.3% you have to take 1-.063=.937 to get the upper percentile. now type into your calculator 2nd, VARS, invNorm, area: .937, mean: 0, and Standard Deviation: 1 which gives you 1.53.
I hope I helped :D
Answer:
The angles that are congruent due to being vertical angles are:
m∠2 and m∠4
m∠1 and m∠3
m∠8 and m∠6
m∠5 and m∠7
Answer:
This may not be that accurate as I am a bit rusty with trigonometry:
tan D: d/f
sin F: f/e
tan F: f/d
cos F: d/e
sin D: d/e
cos D: f/e
Vinegar*16=water
water/16=vinegar
A.
if vinegar is 1/4 then
1/4 times 16=4=water
4 cups
B. 8oz=1cup
80 oz water
water/16=vinegar
80/16=5oz=vinegar
5oz
C.
1qt vinegar
1 times 16=16
16 quart water
find total
vinigar+water=1+16=17 quarts
