Answer:
AC = 3.76
Step-by-step explanation:
take 70 degree as reference angle
using sin rule
sin 70 = opposite / hypotenuse
0.939 = AC /4
0.939 * 4 = AC
3.756 = AC
3.76 = AC

Answer:
The coupon gets you 25% off the usual sales price.
Step-by-step explanation:
First find the discount. Subtract $742.50 from $990, obtaining $247.50.
Determine what percentage this $247.50 discount is of the original price:
$247.50
----------------- = 0.25
$990
The coupon gets you 25% off the usual sales price.
What I can explain to you is that < mean greater than and > means less than..
The probability is 0.336.
To solve this, we need Binomial Probability equation for Repeated Trials.
P = nCr (p)^r (q)^(n-r)
where P = probability (unknown)
n = number of trials (8)
r = number of successes (1)
p = probability of success (.20)
q = probability of failure (0.80)
P = 8C1 (.20)^1 (.80)^7
= 0.336
