Bingel [31]

Answer:

Step-by-step explanation:

The solution to a system of equations is the intersection point of two or more lines on a graph.

In this case, we see that at (1, 3)

Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.

We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.

So the first answer, A, is correct.

Hope this helps!

F = 1.8C + 32

С = -10 ⇒ F = 1.8·(-10) + 32 = 14 ⇒   (-10, 14)
С = 0 ⇒   F = 1.8·(0) + 32 = 32    ⇒ (0, 32)
С = 10 ⇒ F = 1.8·(10) + 32 = 50 ⇒ (10, 50)
С = 20   ⇒ F = 1.8·(20) + 32 = 68   ⇒ (20, 68)

Sales Daria sells televisions. She earns a fixed amount for each television and an additional $25 if the buyer gets an extended

aliina [53]

Answer: Daria earns a fixed amount of $55 for each television.
Step-by-step explanation:
Let a represent the fixed amount that Daria earns for each television.
Daria earns a fixed amount for each television and an additional $25 if the buyer gets an extended warranty. This means that if she sells b televisions with extended warranties, the total amount that she would earn is
ab + 25b
If Daria sells 14 televisions with extended warranties,she earns $1,120. Therefore,
14a + 14 × 25 = 1120
14a + 350 = 1120
14a = 1120 - 350
14a = 770
a = 770/14
a = 55

Vending machines can be adjusted to reject coins above and below certain weights. The weights of legal U.S. quarters have a norm

tigry1 [53]

Answer: The percentage of legal quarters will be rejected by the vending machine = 2.275%

Step-by-step explanation:

Given: The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram.

Let x be the weights of legal U.S. quarters .

Required probability: $P(x5.81)$

$=P(\dfrac{x-\mu}{\sigma}\dfrac{5.81-5.67}{0.07})\\\\=P(z2)\approx0.02275 \ \ \ [By\ P-value\ calculator]$

The percentage of legal quarters will be rejected by the vending machine = 2.275%
