X + x + 1 + x + 2 > 60
3x + 3 > 60
3x > 57
x > 57/3
x > 19

x + 1 = 19 + 1 = 20
x + 2 = 19 + 2 = 21

oldest brother can be at least 21

What is the equation of the line that is perpendicular to the like y=-4x + 7 and passes through the point (8,2)?
Nookie1986 [14]

Answer:

y=\frac{1}{4}x

Step-by-step explanation:

Given equation of line:

y=-4x+7

To find the equation of line perpendicular to the line of the given equation and passes through point (8,2).

Applying slope relationship between perpendicular lines.

m_1=-\frac{1}{m_2}

where m_1 and m_2 are slopes of perpendicular lines.

For the given equation in the form y=mx+b the slope m_2can be found by comparing y=-4x+3 with standard form.

∴ m_2=-4

Thus slope of line perpendicular to this line m_1 would be given as:

m_1=-\frac{1}{-4}

∴ m_1=\frac{1}{4}

The line passes through point (8,2)

Using point slope form:

y_-y_1=m(x_-x_1)

Where (x_1,y_1)\rightarrow (8,2) and m=m_1=\frac{1}{4}

So,

y-2=\frac{1}{4}(x-8)

Using distribution.

y-2=(\frac{1}{4}x)-(\frac{1}{4}\times 8)

y-2=\frac{1}{4}x-2

Adding 2 to both sides.

y-2+2=\frac{1}{4}x-2+2

y=\frac{1}{4}x

Thus the equation of line in standard form is given by:

y=\frac{1}{4}x

An insurance agent has appointments with four prospective clients tomorrow. From past experience the agent knows that the probab
larisa86 [58]

Answer:

0.082

Step-by-step explanation:

Total number of clients = 4

From past experience, the agent knows that the probability of making a sale on any appointment is one out of five = 1/5.

This shows that there are only two possible outcomes, success or failure. It is either she makes a sale on an appointment or she fails to make a sale on the appointment. Therefore, we can use binomial distribution.

For binomial distribution,

P(x=r) = nCr × q^(n-r) × p^r

p = probability of making a sale on any appointment = 1/5 = 0.2

q = probability of not making a sale on any appointment = 1 -1/5 = 0.8

n = 5

x = 3

P(x=3) = 5C3 × 0.8^2 × 0.2^3

= 10×0.6724× 0.012167 =0.082
