If θ is a first-quadrant angle in standard position with P(u, v) = (3, 4), evaluate cos 2 θ . -7/25 -1/5 7/25

Grace [21]

Answer:

-7/25.

Step-by-step explanation:

From the given point P we see that the hypotenuse = √(3*2 + 4^2) = 5.

So cos θ = 3/5

cos 2 θ = 2 cos^2 θ - 1

= 2 * (3/5)^2 -1

= -7/25.

The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of 12. Find the mean for the number

Sever21 [200]

Answer:

mean = 8.4

Step-by-step explanation:

Mathematically, we have the mean as np

This is the product of the number of items per batch by the probability that each of the products will germinate

Mathematically, we have this as:

0.7 * 12 = 8.4

to find the product 3 3/8 * 4 1/9.tara rewrote 3 3/8 as 17/8 amd 4 1/9 as 13/9. she multiplies the fractions to find the product

Ymorist [56]

Answer:

The error Tara made is she rewrote incorrectly 3 3/8 as 17/8 and 4 1/9 as 13/9,

the corrected number can be rewrote as 3 3/8 as 27/8 and 4 1/9 as 37/9.

Step-by-step explanation:

To find the Product of:

$3\frac{3}{8}\times 4\frac{1}{9}$

The Number can be rewrote as,

$\frac{3\times8+3}{8}\times \frac{4\times9+1}{9}\\\\\frac{24+3}{8}\times \frac{36+1}{9}\\\\\frac{27}{8}\times \frac{37}{9}$

Tara made error here she rewrote the number incorrectly 3 3/8 as 17/8 amd 4 1/9 as 13/9.

Now multiplying the fraction we get

$\frac{999}{72}$

Because she rewrote incorrectly which led her answer to multiplication of fraction, the product too was incorrect which she wrote as 221/72.
