Answer:

The number of space shuttle launches the greatest in the year 1985 (C)

Step-by-step Explanation:

According to the graph given in the attachment, the no. of launches made in those years are:

1981: 2
1982: 3
1983: 4
1984: 5
1985: 9
1986: 6

The no. of launches was greatest in the year 1985 and the line graph touches the highest peak in 1985 $.$

Which ordered pair is a solution to the system of equations? Use any method to solve. 4x-y=5, x+y=10

fomenos

Answer:

The ordered pair ( 5, 15) is a solution to the system of given equations.

Step-by-step explanation:

Consider the given equations,

4x-y=5 .......(1)

x+y=10 .......(2)

We have to find the ordered pair which is a solution to the system of given equations.

We solve the system by elimination method,

Adding both equation , to eliminate y ,

⇒ 4x - y +( x+y ) = 5+ 10

⇒ 4x - y + x + y = 15

⇒ 5x = 15

⇒ x = 5

Put x = 5 in equation (1) , and solve for y,

We get,

4x - y = 5 ⇒ 4(5) - y = 5 ⇒ y = 20 - 5 ⇒ y = 15

Thus, the ordered pair ( 5, 15) is a solution to the system of given equations.

Answer:

2 roots.

Step-by-step explanation:

The roots are the same things as the x-intercepts. From -4 to 3, there are two times when the polynomial intersects the x-axis. So, there are 2 roots.

Hope this helps!

The average monthly mortgage payment for all homeowners in a city is $2870. Suppose that the distribution of monthly mortgages p

Anastasy [175]

Answer:

The probability that the monthly mortgage is between 2300 and 3140 is: 0.23167

Step-by-step explanation:

Given

$\mu = 2870$ --- the average

$\sigma = 470$ --- the standard deviation

Required [Missing from the question]

Monthly mortgage is between 2300 and 3140

This is represented as:

$P(2300 < x < 3140)$

This is calculated as:

$P(a< x < b) = P(z_a < Z < z_b)$

$P(2300< x < 3140) = P(z_b < Z < z_a)$

Calculate the z scores

$x = 3140$

$z = \frac{3140 - 2850}{470}$

$z = \frac{290}{470}$

$z = 0.6170$

$x = 2300$

$z = \frac{3140 - 2300}{470}$

$z = \frac{840}{470}$

$z = 1.7872$

So, we have;

$P(2300< x < 3140) = P(1.1787 < Z < 0.6170)$

This is then calculated as:

$P(a < Z < b) = P(Z < a) - P(Z$

$P(a < Z < b) = P(Z < 1.1782) - P(Z$

$P(2300< x < 3140) = P(Z < 1.1782) - P(Z$

Using the z table:

$P(Z$

$P(2300< x < 3140) = 0.96305 - 0.73138$

$P(2300< x < 3140) = 0.23167$
