a(2+b) = -12. What is b?
Please help.

Answer:

$720

Step-by-step explanation:

Given :

Mean, m = 600

Standard deviation, s = 120

Z = (x - m) / s

P(Z > x) = 84%

P(Z > x) = 0.84

Zscore corresponding to P(Z > x) = 0.84 will be -0.994

Hence,

-0.994 = (x - 600) / 120

120 * -0.994 = x - 600

119.28 = x - 600

119.28 + 600 = x

719.28 = x

Hence,

X = $720

Answer:

Value of x = 169°

Step-by-step explanation:

Given:

Number of side = 6

Angles = 151°, x°, 75°, 135°, 115°, 75°

Find:

Value of x

Computation:

Angle sum of Hexagon = 720°

So,

151° + x° + 75° + 135° + 115° + 75° = 720°

x° = 169°

Value of x = 169°

Answer:

4.1 ft

Step-by-step explanation:

All we need to do is substitute "t" as 2 minutes to determine the height:

h = 10.6 + 6.5 sin(850*2),

Remove full rotations of 360 until the angle is between 0 and 360° :

h = 10.6 + 6.5 sin(1700) = 10.6 + 6.5 sin(260)

Now evaluate sin(260) :

h = 10.6 - 6.40125... = 4.1987496

Your solution should be 4.1 ft (though it actually should be 4.2 ft)

Answer:

175%.

Step-by-step explanation:

Given that Jocelyn expects her new software company to increase its sales best year 2 3/4 times their present value, to determine this increase as a percentage, the following calculation must be performed:

3/4 = 0.75

2 + 0.75 = 2.75

Thus, if for example its present value were $ 10, the increase would operate as follows:

10 x 2.75 = 27.5

10 = 100

27.5 = X

27.5 x 100/10 = X

2750/10 = 275

275 - 100 = 175

Thus, an increase of 2 3/4 times would be equal to an increase of 175%.

Answer:

Step-by-step explanation:

Since they are adjacent the sum of the angles must equal 180 degrees.

17x+4+2x+5=180

19x+9=180

19x=171

x=9 making 17x+4=17(9)+4=157 degrees and 2x+5=2(9)+5=23 degrees

So the two angles are 23 and 157

Answer:

The new line will be perpendicular to line EF because both the lines are drawn through the center of the figures (rectangle ABCD and rectangle A'B'C'D') causing both of the lines to intersect each other. Rectangle ABCD will get bigger causing to form rectangle A'B'C'D' because it is dilated with a scale factor of 2. Rectangle A'B'C'D' will contain the new line and line EF.

Hope this helps and stay safe, happy, and healthy, thank you :) !!

•Part A = 1/6 cups of sugar

•Part B = 16/3 pie

•Part A

3/8 cup of sugar = 2 1/4 cups of flour

1 cups of flour = 3/8 : 2 1/4

= 3/8 : 9/4

= 3/8 × 4/9

= 12/72 = 1/6

•Part B

Every pie = 1 1/2 cups of flour

Available = 8 cups of flour

Max pie = 8 : 1 1/2 = 16/3pie

#Now check if the sugar is enough for 16/3 pie

Sugar needed = 16/3 × 1/6 = 8/8

#8/9 is less than 1, so sugar needed is enough. The pie you can make max is 16/3pie

Step-by-step explanation:

Given the data :

ABC = 5.9%

CBS = 7.6%

FOX = 5.5%

NBC = 6.0%

Warner Brothers = 2%

UPN = 2.2%

Other Cable network = 70.8%

From. The piechart distribution, it could be seen that majority of prime time audience watched on other cable network such as CNN and ESPN which Is more than 2 times the percentage that watched on channels such as Fox, ABC, CBS, NBC, Warner Brothers, and UPN which polled about 30% of viewers.

Answer:

-5

Step-by-step explanation:

the slope is change in y over change in x and when y goes down 25 x goes up 5

-25/5=5

Answer:

y-8x=-2

Step-by-step explanation:

so the slope of the perpendicular line has to the negative receprical of the slope of this line which gives

-(-8)=8

let us put all the equations into slope intercept form

a.y=-8x+6

b.y=-1/8x-5

c.y=1/8x-5

d. y=8x-2

y=mx+b

as you can see the only line with a slope of 8 is y-8x=-2

Answer:

  parallel

Step-by-step explanation:

We can put both equations into slope-intercept form to make comparison easier.

  -3x = 3 - y   ⇒   y = 3x +3

  3 +y = 3x -2   ⇒   y = 3x -5

These lines have the same slope, but different y-intercepts.

The lines are parallel.

Answer:

a) Probability of ending up wearing 2 blue socks is 1/11.

b) Probability of ending up wearing no grey socks is 7/22.

c) Probability of ending up wearing at least 1 black sock is 5/11.

d) Probability of ending up wearing a green sock is 0.

e) Probability of ending up wearing matching socks is 19/66.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

In your sock drawer, you have 4 blue socks, 5 gray socks, and 3 black ones. Half asleep one morning, you grab 2 socks at random and put them on. Find the probability you end up wearing: a) 2 blue socks. b) no gray socks. c) at least 1 black sock. d) a green sock. e) matching socks.

The explanation of the answer is now given as follows:

The following are given in the question:

n(B) = number of Blue socks = 4

n(G) = number of Gray socks = 5

n(K) = number of black socks = 3

Therefore, we have:

n(T) = Total number of socks = n(B) + n(G) + n(K) = 4 + 5 + 3 = 12

To calculate a probability, the following formula for calculating probability is used:

Probability = Number of favorable outcomes / Number of total possible outcomes ……. (1)

Since this is a without replacement probability, we can now proceed as follows:

a) 2 blue socks

P(B) = Probability of ending up wearing 2 blue socks = ?

Probability of first pick = n(B) / n(T) = 4 / 12 = 1 / 3

Since it is without replacement, we have:

Probability of second pick = (n(B) – 1) / (n(T) – 1) = (4 – 1) / (12 – 1) = 3 / 11

P(B) = Probability of first pick * Probability of second pick = (1 / 3) * (3 / 11) = 1 / 11

b) no gray socks.

Number of favorable outcomes = n(B) + n(K) = 4 + 3 = 7

P(No G) = Probability of ending up wearing no gray socks = ?

Probability of first pick = Number of favorable outcomes / n(T) = 7 / 12

Since it is without replacement, we have:

Probability of second pick = (Number of favorable outcomes – 1) / (n(T) – 1) = (7 – 1) / (12 – 1) = 6 / 11

P(No G) = Probability of first pick * Probability of second pick = (7 / 12) * (6 / 11) = 7 / 22

c) at least 1 black sock.

Probability of at least one black sock = 1 - P(No K)

Number of favorable outcomes = n(B) + n(G) = 4 + 5 = 9

Probability of first pick = Number of favorable outcomes / n(T) = 9 / 12 = 3 /4

Since it is without replacement, we have:

Probability of second pick = (Number of favorable outcomes – 1) / (n(T) – 1) = (9 – 1) / (12 – 1) = 8 / 11

P(No K) = Probability of first pick * Probability of second pick = (3 / 4) * (8 / 11) = 24 / 44 = 6 / 11

Probability of at least one black sock = 1 - (6 / 11) = 5 / 11

d) a green sock.

n(Green) = number of Green socks = 0

Since, n(Green) = 0, it therefore implies that the probability of ending up wearing a green sock is 0.

e) matching socks.

This can be calculated using the following 4 steps:

Step 1: Calculation of the probability of matching blue socks

P(matching blue socks) = P(B) = 1 / 11

Step 2: Calculation of the probability of matching gray socks

P(matching green socks) = Probability of matching gray socks = ?

Probability of first pick = n(G) / n(T) = 5 / 12

Since it is without replacement, we have:

Probability of second pick = (n(G) – 1) / (n(T) – 1) = (5 – 1) / (12 – 1) = 4 / 11

P(matching gray socks = Probability of first pick * Probability of second pick = (5 / 12) * (4 / 11) = 20 / 132 = 5 / 33

Step 3: Calculation of the probability of matching black socks

P(matching black socks) = Probability of matching green socks = ?

Probability of first pick = n(K) / n(T) = 3 / 12 = 1 / 4

Since it is without replacement, we have:

Probability of second pick = (n(K) – 1) / (n(T) – 1) = (3 – 1) / (12 – 1) = 2 / 11

P(matching black socks) = Probability of first pick * Probability of second pick = (1 / 4) * (2 / 11) = 2 / 44 = 1 / 22

Step 4: Calculation of the probability of ending up wearing matching socks

P(matching socks) = Probability of ending up wearing matching socks = ?

P(matching socks) = P(matching blue socks) + P(matching grey socks) + P(matching black socks) = 1/11 + 5/33 + 1/22 = (6 + 10 + 3) / 66 = 19/66
