Answer:
y=-3x
Step-by-step explanation:
Slope intercept form is written as y=mx+b, where:
m= slope
b= y-intercept
We know the slope and y intercept already, so simply plug them in:
y=-3x+0
We can remove the +0 because it is redundant, therefore the final answer is:
y=-3x
Answer:
sin 15° = 0.2588
Step-by-step explanation:
The half angle formula is:
sin 15°
The double of 15º is 30º. First quadrant, so the sine is positive.
Since 
sin 15° = 0.2588
Height:shadow
so 3.5:1.06 and is the same as 50.5:x
we treat it as a fraction and get
3.5/1.06 and x/50.5
they should be equal
we know that if we multiply two equal fractions, with one flipped, then we will get 1 exg 1/2=4/8 1/2 times 8/4=8/8=1
so 3.5/1.06=x/50.5 3.5/1.06 times 50.5/x=1
176.75/1.06x=1
multiply both sides by 1.06x
176.75=1.06x
divide both sides by 1.06
166.745=x
round up to hundreds place
166.75m=accutal height
The probability that they both only speak Spanish is P = 0.005
<h3>How to find the probability?</h3>
There are 50 people.
We know that:
- 31 of these speak French.
- 2 speak French, German, and Spanish.
- 4 speak French and Spanish.
- 7 speak German and Spanish.
- 8 speak any of the lenguages.
- 10 speak german (and also other lenguages).
Then, the number that speaks only Spanish is:
50 - (31 + 10 + 8 - 3) = 4
(this is, the total number of people minus the ones that speak the other (or neither) lenguages, the "-3" appears there because 3 of the ones that speak German also speak French)
Then the probability that the first randomly selected person speaks Spanish is equal to the quotient between the number that speaks Spanish and the total number:
p = 4/50
For the next person we compute the probability in the same way, but this time there are 3 people that talk Spanish and 49 people in total:
q = 3/49
The joint probability is the product of the two individual ones:
P = (4/50)*(3/49) = 0.005
