Answer:

y=mx+b where m is slope and b is y int

Step-by-step explanation:

1) slope 1/4 and yint 8

2) slope -2 and yint -3

3)slope 0 and y -int is 0 when there is no b

4) Slope is 0 and y int is 7 when there is no B

Two of the most popular options on a certain type of new car are automatic transmission and built-in GPS. Suppose that 90% of al

padilas [110]

Answer:

0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS

Step-by-step explanation:

We solve this question treating these probabilities as Venn sets.

I am going to say that:

Event A: Requesting automatic transmission

Event B: Requesting built-in GPS

90% of all buyers request automatic transmission

This means that $P(A) = 0.9$

82% of all buyers request built-in GPS

This means that $P(B) = 0.82$

77% of all buyers request both automatic transmission and built-in GPS.

This means that $P(A \cap B) = 0.77$

What is the probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS

This is $P(A \cup B)$ , which is given by:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cup B) = 0.9 + 0.82 - 0.77 = 0.95$

0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS

I really need help on this problem respond ASAP

First find the area of the leftmost rectangle:

A=l*w
A=4*2 (the 2 comes from 5-3)
A=8

Then find the area of the rightmost rectangle:

A=l*w
A=3*3 (the second 3 comes from 4-1)
A=9

So when you add 8 and 9, you get 17

Hope this helps

A stainless steel patio heater is a square pyramid. The length of one side of the base is 22.2 in. The slant height of the pyram

Mice21 [21]

Answer:

<h2>The height is 87.5 in</h2>

Step-by-step explanation:

We can solve the height of a square pyramid using the Pythagoras theorem, this is because the slant height the height and the section of the base form a right triangle

the slant height is equivalent to the hypotenuse

the height is equivalent to the opposite

while the base(half) is the adjacent

Given

the base of the pyramid= $22.2 in$

the adjacent is = $\frac{22.2}{2} = 11.1 in$

the slant height (hypotenuse)= $88.2 in$

we know that Pythagoras theorem states that "The sum of the squares of the lengths of the legs of a right triangle ('a' and 'b' in the triangle) is equal to the square of the length of the hypotenuse ('c').

$c^2=a^2 + b^2$
