Answer:
h = 2.7 m
Step-by-step explanation:
The larger triangle and the smaller triangle are similar so ratios of corresponding sides are equal, that is
[tex]\frac{6}{6+12}[/tex] = [tex]\frac{0.9}{h}[/tex] , that is
[tex]\frac{6}{18}[/tex] = [tex]\frac{0.9}{h}[/tex] ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7 m

The evening low temperature in New York in the month of February was -7°F. The following day, the
temperature rose to a high of 25°F. What was the change in temperature that day?
Answer:
32°F
Step-by-step explanation:
Given that,
The low temperature in New York in the month of February was -7°F. The following day, the the temperature rose to a high of 25°F.
We need to find the change in temperature that day.
Change = final temperature - initial temperatur
Change = 25°F - (-7°F)
= 25 +7
= 32°F
so, the required change in temperature is 32°F.

The probability of dry weather (D) = 1⁄2, rain (R) = 1⁄3 and snow (S) = 1⁄6
If it is dry the probability that someone will arrive on time is 4
/5.
If it rains the probability that someone will arrive on time is 2
/5.
If it snows the probability that someone will arrive on time is 1
/10.
Calculate the probability that somebody is late.
=============================================================
Explanation:
Define the following events
D = weather is dryR = weather is rainyS = weather is snowyL = person is lateT = person is on timeWe are given the following probabilities
P(D) = 1/2P(R) = 1/3P(S) = 1/6Then we're further told that "if it is dry, then the probability someone will arrive on time is 4/5". We can condense that into the notation
P(T given D) = 4/5
The "given D" means that we know 100% that event D has occurred. So we're seeing how event T behaves because of D occurring. In other words P(T given D) is the same as saying "What is P(T) when we know D has happened?"
-------------------------
The instructions also mention that "If it rains, the probability someone is on time is 2/5" tells us we have the notation
P(T given R) = 2/5
And also, the probability someone is on time if it is snowy is
P(T given S) = 1/10
due to it saying "If it snows, the probability that someone will arrive on time is 1/10".
-------------------------
To recap so far, your teacher told you these three conditional probabilities
P(T given D) = 4/5P(T given R) = 2/5P(T given S) = 1/10They are conditional due to the "given" as part of the probability. They depend on the given event happening.
Subtract each fraction from 1 and we end up with these complementary probabilities
P(L given D) = 1/5P(L given R) = 3/5P(L given S) = 9/10I'm using the idea that P(A)+P(B) = 1, where A and B are complementary events. One or the other event must happen. Either you are on time, or you are late.
---------------------------
Recall the conditional probability formula is
P(A given B) = P(A and B)/P(B)
which rearranges to
P(A and B) = P(A given B)*P(B)
We'll use this idea to get the following
P(L and D) = P(L given D)*P(D) = (1/5)*(1/2) = 1/10P(L and R) = P(L given R)*P(R) = (3/5)*(1/3) = 1/5P(L and S) = P(L given S)*P(S) = (9/10)*(1/6) = 3/20This means,
P(L) = P(L and D) + P(L and R) + P(L and S) ..... law of total probability
P(L) = 1/10 + 1/5 + 3/20
P(L) = 2/20 + 4/20 + 3/20
P(L) = (2+4+3)/20
P(L) = 9/20 is the probability someone is late

sarah started the school year with 14 drawings in her notebook and draws 5 more each day. whats the linear equation?
Answer:
y = 5x + 14
Step-by-step explanation:
Let x = number of day and y = number of drawings.
She draws 5 drawings per day, so in x days, she draws 5x drawings.
She started with 14 drawings, so the total number of drawings in any day, x, is
5x + 14.
The equation is
y = 5x + 14
