Answer:
Step-by-step explanation:
(84/100)^4(16/100)
(0.84)^4(0.16)^1
To find the inverse of a function, replace x and y in the equation and solve for y. In our case...
x=2y-10
x+10=2y
y=x/2+5
Answer: C
: Miriam multiplied correctly, but her third fraction should be .S
Step-by-step explanation: Miriam used the unit conversation upside down. The 7000 g should have been multiplied by 1oz/28.35g
The grams cancel and the division of 7000 be 28.35 results in 246.91 oz Round to 252oz.
Alternative: 7kg (2.21 lb/kg)(16oz/lb)=252.5oz
The kg and lbs cancel and the amount of ounces remains.
A.
First you have to evaluate (2000* .045) then you take that and multiply by 8 then you add the answer to 2000.
so 2720 is your answer.
Answer:
a)
And we can find this probability with the following difference:
b)
And we can find this probability with the following difference:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Part a
Let X the random variable that represent the diameters of a population 1, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with the following difference:
Part b
And we can find this probability with the following difference:
