48%
quarter=25%
2 nickels=10%
dime=10%
3 pennies=3%
25+10+10+3=48
Answer:
B
Step-by-step explanation:
The exponential decay formula is
y= ab^x
where a is the initial value and
b = 1- decay rate
b= .9
.9 = 1 - decay rate
Subtract 1 from each side
.9-1 = 1-1-decay rate
-.1 = -decay rate
Multiply by -1
.1 = decay rate
Change to a percent
10 % = decay rate
Answer:
1) 
2) 
Step-by-step explanation:
You can factorize the quadratics equations by applying the proccedure shown below:
1) 
Find two number whose sum is 3 and whose product is 2.
These would be 1 and 2.
Rewrite it as folowing:
2) 
Find two number whose sum is 15 and whose product is 50.
These would be 5 and 10.
Therefore, you can rewrite it as folowing:
Answer:
210
Step-by-step explanation:
we have given significance level α=3% =0.03
level of significance is nothing but the chances of rejecting a null hypothesis by the test when it given that it is correct. it is denoted by α it also defined as the
level of significance =1 - confidence level
now statistically significant test =0.03×7000=210
so the expected value of statistical significant is 210
