5 0

Answer:

x-intercept: -1/7

y-intercept: 1/4

Step-by-step explanation:

change equation into standard form: 7x - 4y = -1

set 'x' to zero and solve for y: 0 - 4y = -1

y = 1/4

set 'y' to zero and solve for x: 7x - 0 = -1

x = -1/7

Which of the following equations have no solutions?

Ivahew [28]

Answer:

A, C, D

Step-by-step explanation:

Solve all equations:

A. $33x-25=33x+25$

$33x-33x=25+25\\ \\0=50$

This is incorrect equality, so the equation has no solutions.

B. $33x+25=33x+25$

$33x-33x=25-25\\ \\0=0$

This is correct equality, so the equation has infinitely many solutions.

C. $33x-33=33x+25$

$33x-33x=33+25\\ \\0=58$

This is incorrect equality, so the equation has no solutions.

D. $33x+33=33x+25$

$33x-33x=25-33\\ \\0=-8$

This is incorrect equality, so the equation has no solutions.

Suppose that a recent poll found that 40% of adults in a certain country believe that the overall state of moral values is poor.

shusha [124]

Answer:

Step-by-step explanation:

Let X be the no of adults whose feelings the state of morals is poor.

X has two outcomes and each trial is independent of the other

X is Bin with p = probability for success in each trial =40%=0.40

n=no of adults surveyed = 55

a) The probability that exactly 21 of those surveyed feel the state of morals is poor is

$P(X=21) = 40C21 (0.4)^{21} (1-0.4)^{19} \\=0.03519$

(b) The probability that no more than 22 of those surveyed feel that state of morals is poor is

= $P(X$

$P(X>22)\\=1-0.9811\\=0.0119$

(d) The probability that 15 or 16 believe the state of morals is poor is

= $P(X=15)+P(X=16)\\=0.1228+0.1279\\=0.2507$

A toy company can spend no more than $2,000 on raw materials for plastic trains and metal trains. The raw materials cost $0.80 p

Goryan [66]

Answer:

The gaph is shown in the image below

Step-by-step explanation:

Graph of Inequalities

Let's graph the region of the inequality

$0.8m + 0.4p \leq 2,000$

Since there is no indication, we'll assume the variable p to be in the horizontal axis and m in the vertical axis. Let's solve for m

$\displaystyle m=\frac{2,000-0.4p}{0.8}$

Since both m and p are positive, we can assume

$2,000-0.4p\geq 0$

Or, equivalently

$p \leq 5,000$

Thus, we can give p any value between 0 and 5,000 to get the corresponding values for m. Let's select the values p=0, p=1,000, p=5,000 to get the points

( 0 ; 2,500 ) ( 1,000 ; 2,000 ) ( 5,000 ; 0 )

With these points we can plot the line representing the function. To know which area must be shaded, we only need to test one point below or above the line. If it fulfills the inequality, then the whole area is shaded.

Let's test the point ( 1,000 ; 1,000 )

$0.8\cdot 1,000 + 0.4\cdot 1,000 \leq 2,000$

$1,200 \leq 2,000$

Since the condition is met, the area below the line must be shaded as the solution of the inequality
