There is 5 yellow 3 red 4 green 2 blue and 2 white what is the probability of picking white then green

Answers

Answer:

2 (I think)

Step-by-step explanation:

4-2=2

Answer:

1/30

Step-by-step explanation:

the probability of picking white is 2/16 simplified to 1/8

the probability of picking a green would equal to 4/15

notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.

you would then multiply

1/8 x 4/15

= 4/120

simplified to

1/30

14. A red dress priced at Php 550.00 is marked 15% off. How much will be the discount?
a. P 82.50
b. P 8.50
c. P 825
d. P 85
​

Answers

Answer:

the answer for the discount is A. P 82.50

The discount is P 82.50.
Step-by-step explanation:
Finding the Discount
The discount refers to the amount being deducted from the original price. It is determined by the rate. To find the discount, multiply the rate by the original price.
Given:
original price - P 550.00
rate - 15%
Equation:
Remember to convert the rate to decimal by dividing it by 100.
P 550.00 × 0.15 = N
Solution:
P 550.00 × 0.15 = P 82.50
Final Answer:
P 82.50

Can someone plz help me with this??

Answers

Answer:

it's the second choice (3=3)

Answer:

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (1, 3 ) into the partial equation

3 = - 1 + c ⇒ c = 3 + 1 = 4

y = - x + 4 ← equation of line

A tree casts a shadow 31 feet long when the angle of
elevation of the sun is 58º. Find the height of the tree.

Answers

Answer:

x=24.2198542

ROUND IF NEEDED

Step-by-step explanation:

We are trying to find the height of the tree or the vertical side

We are given

The angle of elevation or the angle at the ground ,38The horizontal length, 31.

Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle

we are going to use tangent

[tex] \tan(x) = \frac{opp}{adj} [/tex]

plug 38 in for x or theta, x for opp side and 31 for adjacent side

[tex] \tan(38) = \frac{x}{31} [/tex]

Multiply 31 by both sides to find x

x=24.2198542

ROUND IF NEEDED.
