Supersonics Records plans to market a new record for a comeback artist nationwide. Management believes that there is a 70% chance that the new record will be a hit and, therefore, a 30% chance that the new record will be a miss. However, before resources are committed to market this new record nationwide, management will ask Mr. Deejay, a well-known authority in the music scene, to predict whether the new record will be a hit or a miss. Mr. Deejay's past predictions were quite impressive-che correctly predicted a hit record 80% of the time and incorrectly predicted a hit record only 10% of the time. Let H = The new record is actually a hit M = The new record is actually a miss DH = Mr. Deejay predicts the new record will be a hit Therefore, P(H) = 0.70 P(M) = 0.30 P(DH/H) = 0.80 P(DH/M) = 0.10 Based on these information, what is P(H and DH)? (That is, what is the probability that the new record is actually a hit (H) AND Mr. Deejay predicts the new record will be a hit (DH)?)

Hello your question is poorly written attached below is the complete question

answer : 166.41 kph

Step-by-step explanation:

Given data :

Drone speed = 180 kph

Altitude of drone  = 1 km

distance of motorcycle decreases at  200 kph

calculate the speed in kph of the motorcycle

attached below is a detailed solution of the problem

Answer:

1 3/4 cups of wheat flour is in the bowl

Step-by-step explanation:

x + 2/3 = 2 5/12

First, convert the 2/3 to 12ths by multiplying numerator and denominator by 4 = 8/12

Then convert the 2 5/12 to an improper fraction 29/12

x + 8/12 = 29/12

subtract 8/12 from both sides

x = 21/12 = 1 9/12 = 1 3/4

Answer:The answer is A)11(9)(4)

Step-by-step explanation:

If you have 9(4)(11) then is would be the one that look just like it but the number are moved like 11(9)(4)

Answer:

The Answer is 11 (9 + 4)

Answer:

150 trees

Step-by-step explanation:

If 40% of the trees is 300, you'd expect that 20% (half the percentage) is also half the trees.

Answer:

150 trees

Step-by-step explanation:

40 % / 2 = 20%

300 / 2 = 150 trees

Answer:

area is 15 square units

16 units for perimeter

Step-by-step explanation:

perimeter refers to the sum of all of the sides

if the width of this rectangle is 3 squres, and the length of the square is 5 squares then

3+3+5+5 = 16 units for perimeter

for area = length x width

since length = 5 and width = 3 then

5x3=15

so area is 15 square units

Answer:

8

Step-by-step explanation:

6÷[tex]\frac{3}{4}[/tex]

To make it easier, let's write 6 as a fraction.

[tex]6=\frac{6}{1}[/tex]

Now we get:

[tex]\frac{6}{1}[/tex]÷[tex]\frac{3}{4}[/tex]

Flip the numbers of [tex]\frac{3}{4}[/tex] and multiply instead of dividing and we get:

[tex]\frac{6}{1} *\frac{4}{3}=\frac{24}{3} =8[/tex]

Answer: 8

Step-by-step explanation:

6/1 * 3/4

cross multiply

8

Answer:

y=-2x+8

Step-by-step explanation:

So I select 2 points:

(0,8) and (4,0)

so then I find the slope.

m = [tex]\frac{8-0}{0-4} \\=\frac{8}{-4} \\=\frac{2}{-1} \\=-2[/tex]

m = -2

Then the b (y-intercept) is 8, so equation is:

y=-2x+8

Hoped I helped ([P.S. I love math!)

Answer:

3/70

Step-by-step explanation:

change 1/10 and 1/7 so the denominator (bottom number) is the same.  1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.

Answer:

34.4

Step-by-step explanation:

(54/11) --> ratio of one side of the larger triangle to the smaller one multiplied by 7 = 34.36363636... Rounding it to the nearest tenth is 34.4

Answer:

the three consecutive numbers are 14, 15, 16

Answer:

Since the consecutive numbers, so the first one is x, the next one is x+1, and so on....I hope this will help

Step-by-step explanation:

x + (x + 1) + (x + 2) = 45

x + x + 1 + x + 2 = 45

3x + 3 = 45

3x = 42

x = 14

Now that we know x = 14, let's add one to it.

x + 1 = 14 + 1 = 15.

Now we have our middle number, which is 15. You can always check your answer by adding 14 + 15 + 16 = 45. Whoo!

Answer:

Ikr

Step-by-step explanation:

I used to be able to know what 1 + 1 but now I have no idea how to solve that

(Im jk btw lol)

First let's reduce the feet to miles

there are 5280 feet in a mile therefore

26400 feet=5 miles

31680 feet=6 miles

Jet A(the first jet) descends 5 miles in 96 miles

Jet B(the second jet) descends 6 miles in 120 miles

We can compare these as fractions to see which is steeper. This can be viewed as slope and the origin (0,0) is the airport.

slope: 6/120=?=5/96

1/20=?=5/96

Now we know that 5/100 =1/20 so 5/96 must be bigger than 5/100 because you are dividing by a smaller number.

so 1/20<5/96

So Jet B is descending steeper than Jet A.

As for linear model, I don't exactly know what your teacher means but I think I actually used the linear model when I'm thinking of steepness as slope in the coordinate plane, I will include a picture.

In this extremely zoomed out graph, you can see the blue line is just slighly higher than the red line(slope as in explanation is way easier to tell) this could be seen as the linear model) :) Hope it helped!

Answer:

205in. squared
