ANSWER
C. x=7
EXPLANATION
The given exponential equation is
We rewrite the right hand side as 3 raised to exponent 2.
Observe that the base of both sides of the equation are equal.
We now equate the exponents.
Solve for x,
The correct choice is C.
2 3/5 divide 6
pretend that 6 has a denominator which is 6
2 3/5 divide 6/1
make 2 3/5 into a improper fraction
multiply the whole number and denominator together
2*5=10
add 10 with the numerator
10+3=13
13/5 divide 6/1
always flip over the second fraction
13/5*1/6
13*1=13- multiply the numerators together
5*6=30 - multiply the denominators together
13/30- as a decimal=0.43333 ( the 3s continue forever )
answer:
0.433333
Answer:
P-value is lesser in the case when n = 500.
Step-by-step explanation:
The formula for z-test statistic can be written as
here, μ = mean
σ= standard deviation, n= sample size, x= variable.
From the relation we can clearly observe that n is directly proportional to test statistic. Thus, as the value of n increases the corresponding test statistic value also increases.
We can also observe that as the test statistic's numerical value increases it is more likely to go into rejection region or in other words its P-value decreases.
Now, for first case when our n is 50 we will have a relatively low chance of accurately representing the population compared to the case when n= 500. Therefore, the P-value will be lesser in the case when n = 500.
i.e truch weighs 500 lbs so the car weighs 50lbs. lets say thw truck goes 2 mph so thatll be 1000 for the car to reach 1000 you have to divide and youll get 20. so the car has to be ten times as fast as the truck
