Answer:

a different inverse function

Step-by-step explanation:

If $f^{-1}(x)=-\frac{1}{5}x$ then $f^{-1}(x)=\frac{1}{5}x$ is a different inverse function.

The second (inverse) function is the first reflected over the y-axis.

Find the probability of at least 2 girls in 6 births. assume that male and female births are equally likely and that the births

faust18 [17]

Sounds like a problem in binomial probability. What do you think?

Here the # of experiments is 6, so n = 6. The probability of a baby girl being born is 0.50.

Using my TI-83 Plus calculator:

binompdf(6, 0.5, 2) = 0.234
binompdf(6, 0.5, 3) = 0.313
binompdf(6, 0.5, 4) = 0.234
binompdf(6, 0.5, 5) = 0.094
binompdf(6, 0.5, 6) = 0.016

To get the prob. of at least 2 girls in 6 births, add up the 5 probabilities given above:

P(at least 2 girls in 6 births) = 0. ???

Jadyn is looking to purchase a home for $182,000 and will make a $40,000 down payment in order to borrow the remainder. Jadyn’s

AysviL [449]

Answer: Jadyn’s monthly mortgage payment is $812

Step-by-step explanation:

The cost of the house is $182,000.

The down payment made is $$40,000. The balance to be paid would be

182000 - 40000 = $142000

We would apply the periodic interest rate formula which is expressed as

P = a/[{(1+r)^n]-1}/{r(1+r)^n}]

Where

P represents the monthly payments.

a represents the amount of the loan

r represents the annual rate.

n represents number of monthly payments. Therefore

a = $142000

r = 0.00351/12 = 0.000293

n = 12 × 15 = 180

Therefore,

P = 142000/[{(1+0.000293)^180]-1}/{0.000293(1+0.000293)^180}]

142000/[{(1.000293)^180]-1}/{0.000293(1.000293)^180}]

P = 142000/{1.054 -1}/[0.000293(1.054)]

P = 142000/(0.054/0.0003088)

P = 142000/174.87

P = $812

Assume that a procedure yields a geometric distribution where the probability of success is 19%. Use the geometric probability f

Rudiy27

The probability that the first success occurs on the third trial is 0.125.

Answer: Option C

<u>Step-by-step explanation:</u>

The probability of success is given by the geometric distribution formula:

$P(X=x)=p \times q^{x-1}$

Where,

p = probability of success for single trial.

q = probability of failure for a single trial (1-p)

x = the number of failures before a success.

P(X = x) = Probability of x successes in n trials.

<u>Given: </u>

p = 19% = 0.19

q = 1 – p = 1 – 0.19 = 0.81

x = 3

We want to find the probability that the first success occurs on the third trial so,

$P(X=3)=0.19 \times 0.81^{(3-1)}$

$P(X=3)=0.19 \times 0.81^{2}$

$P(X=3)=0.19 \times 0.6561=0.125$
