Leokris [45]3 years ago
5 0

Answer:

B.

Step-by-step explanation:

3/12 reduces to 1/4.

1/2 alone is greater than 1/4, so when 2/10 is added to 1/2, it is certainly greater than 3/12.

Answer: B.

5.8 km is how many meters
stepan [7]

Answer:

5,800m

Step-by-step explanation:

1 km = 1000 m

Use the SBD (small to big, divide) and BSM (big to small, multiply) method.

So, 5.8 X 1000, as we are converting km(big) to m(small) and move the decimal point corresponding to the number of zeroes = 5800m

GREYUIT [131]

Answer:

Step-by-step explanation:

Given the expression (4z^8)^{-3}, to evaluate this, we will use one of the law of indices as shown;

(a^m)^n = a^{mn}

4^{-3} * z^{8*-3}

= \frac{1}{4^3} * z^{-24}\\ \\= \frac{1}{64} * \frac{1}{z^{24}}\\  \\= \frac{1}{64z^{24}}

Mario's error was that she did not raise the value of 4 to the power of -3. She only raised z^8 to the power of -3 when it is supposed to affect both 4 and z^8

A gray-scale digital camera with 1,000,000 pixels takes a picture (the picture is made of 1,000,000 parts and each part has a ce
Novay_Z [31]
Let X be a random variable representing the mean gray scale of each pixel.
P(110 ≤ X ≤ 140) = P(X < 140) - P(X < 110) = P(z < (140 - 125)/15) - P(z < (110 - 125)/15) = P(z < 1) - P(z < -1) = P(z < 1) - [1 - P(z < 1)] = 2P(z < 1) - 1 = 2(0.84134) - 1 = 1.68268 - 1 = 0.68268

Number of pixels that have gray scale of between 110 and 140 = 0.68268 x 1000000 = 682680 = approximately 680,000
