Answer:

60 cm

Step-by-step explanation:

remember, the area of a triangle is found by

1/2 b h

or half of the base times the height

so using that plug in the values:

the base is made of two 5s; 2* 5 is 10 so the base is 10cm long

the height is 12cm

so

1/2 * 12 * 10

= 6 * 10

= 60

Answer:

0.087 = 8.7% probability that this person made a day visit.

0.652 = 65.2% probability that this person made a one-night visit.

0.261 = 26.1% probability that this person made a two-night visit.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Made a purchase.

Probability of making a purchase:

10% of 20%(day visit)

30% of 50%(one night)

20% of 30%(two night).

So

$p = 0.1*0.2 + 0.3*0.5 + 0.2*0.3 = 0.23$

How likely is it that this person made a day visit?

Here event B is a day visit.

10% of 20% is the percentage of purchases and day visit. So

$P(A \cap B) = 0.1*0.2 = 0.02$

So

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.02}{0.23} = 0.087$

0.087 = 8.7% probability that this person made a day visit.

A one-night visit?

Event B is a one night visit.

The percentage of both(one night visit and purchase) is 30% of 50%. So

$P(A \cap B) = 0.3*0.5 = 0.15$

So

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.15}{0.23} = 0.652$

0.652 = 65.2% probability that this person made a one-night visit.

A two-night visit?

Event B is a two night visit.

The percentage of both(two night visit and purchase) is 20% of 30%. So

$P(A \cap B) = 0.2*0.3 = 0.06$

Then

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.06}{0.23} = 0.261$

0.261 = 26.1% probability that this person made a two-night visit.

Find M so that the lines with equations -2x + My = 5 and 4y + x = -9 are<br>perpendicular.

vfiekz [6]

<h3>Answer: M = 1/2</h3>

=====================================================

Work Shown:

Solve the second equation for y to get the following

4y+x = -9

4y = -x-9

y = (-x-9)/4

y = (-x)/4-9/4

y = (-1/4)x-9/4

The equation is in y = mx+b form where m = -1/4 is the slope of this line. Note: this is not the same as the uppercase M we're after; the lowercase m is conventionally used as the general slope term.

---------

The slope of the second line is -1/4. Flip the fraction to get -4/1 = -4, then flip the sign to go from -4 to +4 or just 4.

This means the slope of the first line must be 4 in order for the two lines to be perpendicular. The two perpenicular slopes multiply to -1. We see that (-1/4)*(4) = -1.

---------

Let's solve the first equation for y

-2x + My = 5

My = 2x+5

y = (2x+5)/M

y = (2x)/M + 5/M

y = (2/M)x + 5/M

The slope here is 2/M. It must be equal to 4, so lets equate and solve for M

2/M = 4

2 = 4M

4M = 2

M = 2/4

M = 1/2

which is our final answer

Can anyone help me please. This is due at 12. There is an attachment just so you know.

n200080 [17]

Answer: x<3

Step-by-step explanation: Hi! First you should simplify the equation. You can do this by subtracting 6 from both sides of the equation. This would give you -9<-3x. After that, flip the equation and write it as -3x<-9. Then, divide by -3, which gives you x<3. Hope this helps! :D

Please help In the example of the racetrack, what was the average displacement at the end of the race?

andreev551 [17]

Answer:The Indianapolis Motor Speedway is an automobile racing circuit located in Speedway, Indiana (an enclave suburb of Indianapolis) in the United States. It is the home of the Indianapolis 500 and the Verizon 200,[4] and formerly the home of the United States Grand Prix. It is the largest sports venue in the world. It is located on the corner of 16th Street and Georgetown Road, approximately six miles (10 km) west of Downtown Indianapolis.

Constructed in 1909, it is the second purpose-built, banked oval racing circuit after Brooklands and the first to be called a 'speedway'. It is the third-oldest permanent automobile race track in the world, behind Brooklands and the Milwaukee Mile. With a permanent seating capacity of 257,325,[1] it is the highest-capacity sports venue in the world.[5]

Considered relatively flat by American standards, the track is a 2.5-mile-long (4.0 km) rectangular oval with dimensions that have remained essentially unchanged since its construction. It has two 5⁄8-mile-long (1,000 m) straightaways, four geometrically identical 1⁄4-mile (400 m) turns, connected by two 1⁄8-mile (200 m) short straightaways, termed "short chutes", between turns 1 and 2, and between turns 3 and 4.
