Answer:

B

Step-by-step explanation:

6n - 2(4n + 7) + 4= -2 firstly you open the bracket

6n - 8n - 14 + 2 = -2 then you collect the like terms

6n - 8n= -2 + 14 - 4 then add and subtract and divide by the coefficient

-2n= 12 - 4

-2n = 8

= n = 8 ÷ -2

n = -4

A bank loaned out $8200, part of it at a rate of 7.9% per year and the rest of it at a rate of 7.4% per year. The total amount o
Lady bird [3.3K]

The amount that the bank loaned out at 7.9% is $1,574.00

How do represent the amounts lent at different rates?

On the assumption that x amount was loaned at 7.9% and that the remaining amount, (8,200-x) was loan out at 7.4%, we can determine the interest charged on each loan as the loan multiplied by the interest rate

interest on 7.9% loan=7.9%*x=0.079x

interest on 7.4% loan=7.4%*(8200-x)

interest on 7.4% loan=606.80-0.074x

total interest=0.079x+606.80-0.074x

total interest=0.005x+606.80

total interest on loans=614.67

614.67=0.005x+606.80

614.67-606.80=0.005x

7.87=0.005x

x=7.87/0.005

x=amount loaned at 7.9%=$1,574.00

y=$8200-$1574

y=$6,626.00

The weights of college football players are normally distributed with a mean of 200 pounds and a standard deviation of 50 pounds
belka [17]

Answer:

P(170

And we can find this probability with this difference:

P(-0.6

Step-by-step explanation:

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

X \sim N(200,50)  

Where \mu=200 and \sigma=50

We want to find the following probability:

P(170

And we can use the z score formula given by:

z=\frac{x-\mu}{\sigma}

And using this formula we got:

P(170

And we can find this probability with this difference:

P(-0.6
