HELP PLEASE!!!!!!!A box contains 4 oranges, 9 apples, and 3 pears. Liliana selects a piece of fruit from the box at random.

What is the probability that she selects an orange or a pear?

Answers

Answer: The probability that she selects an orange or a pear is 7/16.

Step-by-step explanation:

Given number of oranges = 4,

Apples = 9,

Pears = 3,

Total number of fruits = 4 + 9 + 3 = 16,

If she selects a piece of fruit from the box at random,

Then, the probability that she selects an orange or a pear

= The probability of oranges + The probability of oranges

$=(^4C_1)/(^(16)C_1)+(^3C_1)/(^(16)C_1)$

$=(4)/(16)+(3)/(16)$

$=(7)/(16)$

7 out of 16 . so therefore you add the number of oranges and pairs then on the number 16 you just add all pieces of friut

Use the squared identities to simplify sin^2x cos^2x

Answers

Answer:

$(1-cos^2(2x))/(4)$

Step-by-step explanation:

We have the following expression

$sin^2x *cos^2x$

Whe know that:

$sin^2(x) = (1-cos(2x))/(2)\n\ncos^2(x)=(1+cos(2x))/(2)$

Now replace these equations in the main expression and simplify

$((1-cos(2x))/(2))*((1+cos(2x))/(2))$

$(((1-cos(2x))(1+cos(2x)))/(4))$

Apply the following property

$(a + b) (a-b) = a ^ 2 -b ^ 2$

Then

$(((1-cos(2x))(1+cos(2x)))/(4))=(1^2-cos^2(2x))/(4)$

Finally:

$(((1-cos(2x))(1+cos(2x)))/(4))=(1-cos^2(2x))/(4)$

I need help solving this problem 7/10 + 4 =

Answers

7/10=.7
.7+4=4.7
that is the answer

If you need in fractions...
7/10 + 4 = 4 and 7/10
You get this by just adding the whole number to the fraction. Or, do it this way...
7/10 + 4/1 : find LCD to get 10.
=7/10 + 40/10
= 47/10
= 4 and 7/10
