Need help!!! What’s the correct choice!!

Answer:

The Equation would be $4 + $3.50x = y

Step-by-step explanation:

Answer:

x = 11

Step-by-step explanation:

The two angles form a straight line so they add to 180

4x+15 + 11x = 180

Combine like terms

15x+15 = 180

Subtract 15 from each side

15x+15-15 = 180-15

15x = 165

Divide by 15

15x/15 =165/15

x = 11

Answer:

12.3693169

Step-by-step explanation:

x^2+y^2=r^2

(12)^2=(3)^2=sqroot(153)

=12.3693169

Step-by-step explanation:

probability of not getting six=5/6

is your answer

Given:

Cards labelled 1, 3, 5, 6, 8 and 9.

A card is drawn and not replaced. Then a second card is drawn at random.

To find:

The probability of drawing 2 even numbers.

Solution:

We have,

Even number cards = 6, 8

Odd numbers cards = 1, 3, 5, 9

Total cards =  1, 3, 5, 6, 8 and 9

Number of even cards = 2

Number of total cards = 6

So, the probability of getting an even card in first draw is:

[tex]P_1=\dfrac{\text{Number of even cards}}{\text{Number of total cards}}[/tex]

[tex]P_1=\dfrac{2}{6}[/tex]

[tex]P_1=\dfrac{1}{3}[/tex]

Now,

Number of remaining even cards = 1

Number of remaining cards = 5

So, the probability of getting an even card in second draw is:

[tex]P_2=\dfrac{\text{Number of remaining even cards}}{\text{Number of remaining total cards}}[/tex]

[tex]P_2=\dfrac{1}{5}[/tex]

The probability of drawing 2 even numbers is:

[tex]P=P_1\times P_2[/tex]

[tex]P=\dfrac{1}{3}\times \dfrac{1}{5}[/tex]

[tex]P=\dfrac{1}{15}[/tex]

Therefore, the probability of drawing 2 even numbers is [tex]\dfrac{1}{15}[/tex]. Hence, the correct option is (b).

Answer:

Option 3 and 4.

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation[/tex]

Given that mean (μ) = 82, standard deviation (σ) = 5

1) For x = 74:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{74-82}{5} =-1.6[/tex]

Option 1 is incorrect

2) For x < 87

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{87-82}{5} =1[/tex]

From the normal distribution table, P(x < 87) = P(z < 1) = 0.8413 = 84.13%

Option 2 is incorrect

3) For x = 95:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{95-82}{5} =2.6[/tex]

Option 3 is correct

4) For x < 77

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{77-82}{5} =-1[/tex]

From the normal distribution table, P(x < 77) = P(z < -1) = 0.16 = 16%

Option 4 is correct

5) For x > 92

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{92-82}{5} =2[/tex]

From the normal distribution table, P(x > 92) = P(z > 2) = 1 - P(z < -2) = 1 - 0.9772 = 0.0228 = 2.28%

Option 5 is incorrect

Answer:

$72.33

Step-by-step explanation:

125 * 0.45 = 56.25

125 - 56.25 = 68.75 (marked off price)

68.75 * 1.052 = 72.33 (add sales taxes and round off)

Final price $ 72.33

Answer:

3:2

Step-by-step explanation:

The circumference is a distance.  The ratio of the distance is the same as the scale factor.  The ratio of the areas is the ratio of the scale factor squared and the volume is the scale factor cubed.

Answer:

i can see the actual question, what is it?

In right triangles one of the angles will always be 90 degrees.

So if you had a right triangle with one right angle, a number, and a number, they always have to add up to 90 degrees as well, because a triangle is always 180 degrees

so  

Answer:

= -11/4

Step-by-step explanation:

To find the slope given two points

m = ( y2-y1)/(x2-x1)

   = (6 - -5)/(-2 -2)

   = (6+5)/(-2-2)

    = 11/-4

    = -11/4

Answer:

-2.75 (-2 3/4)

Step-by-step explanation:

you can do rise of a run whenever you have two points so you have 6-(-5)/-2-2 and solve so -11/4 and that equals -2.75.

Answer:

0.1015, 0.11, 0.7, 0.715

Answer: B

Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.

Answer:

AB ≈ 3.14 in

Step-by-step explanation:

arc AB is calculated as

AB = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{30}{360}[/tex]

     = 2π × 6 × [tex]\frac{1}{12}[/tex]

     = 12π × [tex]\frac{1}{12}[/tex]

     = π ≈ 3.14 in ( to the nearest hundredth )

I hope it's the right answer

Answer:

Carly will have to spend $7.25

Step-by-step explanation:

We know that:

1 pound of turkey = $5.80

To find how much 1.25 pounds of turkey will cost, multiply:

5.80 x 1.25 = 7.25

Therefore, 1.25 pounds of turkey will cost $7.25

We know that a^b ÷ a^ c = a^ ( b-c)

5^12 ÷ 5^4 = 5^ (12-4) = 5^8

Answer:

9 buttons in package 34

Step-by-step explanation:

There are 26 buttons in each box.

26 * 33 = 858 for the first 33 full boxes

867 - 858 = 9 buttons in the 34th box

B = buttons per box

33*B<867 --> B < 26.27

34*B>867 --> B > 25.5

So 25.5 < B < 26.27, therefore B = 26 buttons per box

Answer:

48 cm

Step-by-step explanation:

percent x meters x centimeters in meters

.12 x 4 x 100

Answer:

48 cm

Step-by-step explanation:

12/100 * 4 = 48 meters

1 meter = 100 cm

0.48 m = x                        Cross Multiply

1*x = 0.48 * 100

x = 48 cm

Answer:

observations and quadratic formula

Step-by-step explanation:

The given data is :

195, 194, 191, 190, 238, and 192

Mean = (sum of observations)/(total no. of observations)

[tex]\text{Mean}=\dfrac{195+194+191+190+238+192}{6}\\\\=200[/tex]

So, the mean is the best measure. Also, w can find median as follows.

arranging in order : 190,191,192, 194, 195,238

Here, n = 6

[tex]\text{Median}=\dfrac{\dfrac{n}{2}^{th}+(\dfrac{n}{2}+1)^{th}}{2}\\\\\text{Median}=\dfrac{\dfrac{6}{2}^{th}+(\dfrac{6}{2}+1)^{th}}{2}\\\\=\dfrac{3^{th}+4^{th}}{2}\\\\=\dfrac{192+194}{2}\\\\=193[/tex]

Hence, this is the required solution
