Answer:

Step-by-step explanation:

It has the correct ration of red wax to white wax.

If for every 12 mL of red wax there's 5mL of white wax, with 36 mL, which is triple the amount a pink crayon calls for, then we also have to triple the white wax. 5 mL times 3 is 15 mL. Therefore, D is correct.

99 POINTS, NEED HELP WITH ALGEBRA

Tanya [424]

1 is in picture above.

$average \: rate = \frac{f(4) - f(1)}{4 - ( - 1)} = \frac{5}{4 - ( - 1)} = 1$

3. In the picture...

4. In the picture...

5. Parts A and B are true.

$average \: rate = \frac{f(0) - f( - 10)}{0 - ( - 10)} = \frac{( - 6) - 184}{0 - ( - 10)} = \frac{ - 190}{10} = - 19$

7. The axis symmetry equation of

$y = a {x}^{2} + bx + c$

$x = \frac{ - b}{2a}$

So it would be x=-3/4

$y = {(x - 6)}^{2} + 10$

T=(6, 10) vertex coordinates...

In a random sample of 500 handwritten zip code digits, 464 were read correctly by an optical character recognition (OCR) system

In-s [12.5K]

Answer:

z= 2.38

P = 0.008656

Step-by-step explanation:

Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072

We formulate our null and alternate hypothesis as

H0 = 0.9 ; H0 > 0.9

The degree of confidence = 90%

z₀.₀₅ = 1.645 for α= 0.05

We use the test statistic

z= x- np/√npq

z= 466-500 *0.9/ √500 * 0.9(1-0.9)

z= 466- 450/ √45

z= 16/6.7082

z= 2.38

As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.

If H0 is true the P value is calculated as

P = 1- Ф( 2.38)

P = 1-0.991344=0.008656

<h3>Answer: Choice C</h3>

======================================================

Explanation:

The x coordinate of the preimage point Q is x = 6.

The x coordinate of the image point Q' is x = 21.

The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2

You'll get this same value if you do the same steps with the y coordinates.

Therefore, the scale factor is 7/2 and the dilation rule is $(x,y) \to \left(\frac{7}{2}x, \frac{7}{2}y\right)$

Note: 7/2 = 3.5
