katen-ka-za [31]

Answer:

#1; $y = -\frac{7}{2}x+5$

Step-by-step explanation:

$7x+2y=10$

$2y = -7x + 10$

$\frac{2y}{2} = -\frac{7x}{2} + \frac{10}{2}$

$y = -\frac{7}{2}x + 5$

Danny invests $10,000 in a savings account that pays 3.5% simple interest. If Danny does not make any additional deposits or wit

SashulF [63]

Answer:

Danny will have 12,450 in his savings account

Step-by-step explanation:

P is the principal amount, $10000.00.

r is the interest rate, 3.5% per year, or in decimal form, 3.5/100=0.035.

t is the time involved, 7....year(s) time periods.

So, t is 7....year time periods.

To find the simple interest, we multiply 10000 × 0.035 × 7 to get that:

The interest is: $2450.00

10000.00 + 2450.00 = 12450.00.

Suppose your waiting time for a bus in the morning is uniformly distributed on [0, 8], whereas waiting time in the evening is un

ycow [4]

Answer:

41/3

Step-by-step explanation:

given that your waiting time for a bus in the morning is uniformly distributed on [0, 8], whereas waiting time in the evening is uniformly distributed on [0, 10] independent of morning waiting time.

Sum of both waiting times = X+Y

Where X = morning wait time is U(0.8) and

Y = evening wait time is U(0,10)

Since X and Y are independent

Var(x+y) = Var(x)+Var(y)

Var(x) = $\frac{8^2-0^2}{12} \\=\frac{16}{3}$

Var(Y) = $\frac{10^2-0^2}{12} \\=\frac{25}{3}$

Var(x+y) $\frac{16+25}{3} \\=\frac{41}{3}$
