Do you mean y=mx+b, do you have a slope? If not then you’d just put a dot on the 4 on the y axis :)

4. Entry to a certain University is determined by a national test. The scores on this test are normally distributed with a mean

Karo-lina-s [1.5K]

Answer:

Yes, Tom must be admitted to this university.

Step-by-step explanation:

We are given that the scores on national test are normally distributed with a mean of 500 and a standard deviation of 100.

Also, we are provided with the condition that Tom wants to be admitted to this university and he knows that he must score better than at least 70% of the students who took the test.

Let, X = score in national test, so X ~ N( $\mu=500 , \sigma^{2} = 100^{2}$ )

The standard normal z distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

Now, z score of probability that tom scores 585 is;

Z = $\frac{585-500}{100}$ = 0.85

Now, proportion of students scoring below 85% marks is given by;

P(Z < 0.85) = 0.80234

This shows that Tom scored 80.23% of the students who took test while he just have to score more than 70%.

So, it means that Tom must be admitted to this university.

$5000 was invested into an account that earns an annual rate of 4.75%. If money is compounded monthly, how much will the account

Aleonysh [2.5K]

Answer:

$5764.14

Step-by-step explanation:

The future value formula is useful here.

FV = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

FV = $5000(1 +.0475/12)^(12·3) = $5764.14

The account will be worth $5764.14 after 3 years.

Step-by-step explanation:

increase in 15% therefore 1.15% of principal amount

$27355 times 1.15= $31458.25

$31458.25 times 1.15=$36,176.8975

$36,176.8975 times 1.15= $41603.53563

round all answers to the nearest dollar and you get

$31, 458, $36, 177, $41,604

Using I=PRT/100
replacing the given information;
(p+prt)=P×r×t

⇒p+prt=P×rt
P=(p+prt)/(rt)
Principal(P)= (p/rt)+p
=p((1/rt)+1)
