Answer: I’m pretty sure it’s 80

Step-by-step explanation:

Because the very top triangle is 4x3 which is 12 then the rectangle under it is 6x3 which is 18 then the triangle under that is 5x3 which is 15 and the triangle on the left is also 15 and the square in the middle is 4x5 which is 20 and add it all up 12+18+15+15+20=80 sry if that’s confusing.

Answer:

74 is the answer

Step-by-step explanation: You should find the area of each shape and add all the areas together to get the full area of the shape.

(base x height)+(length x breath)+(1/2 x base x height)
(10x5)+(6x3)+(1/2x3x4)

50+18+6

74 ← this is the full area of the shape

and, remember when finding the area of a triangle you should always multiply 1/2 too for example- ( 1/2 x base x height )

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

The equation of a circle:

\((x+2)^2+(y-3)^2 = 16\)

Step-by-step explanation:

The equation of a circle:

\((x-h)^2+(y-k)^2 = r^2\)

(where the center is known as \((h,k)\) and the radius, known as \(r\)).

-Since you already have the center and the radius, use them for the equation of a circle:

Center: \((-2,3)\)

Radius: \(4\)

\((x+2)^2+(y-3)^2 = 4^2\)

After you have the equation of a circle, simplify the radius by the exponent \(2\) :

\((x+2)^2+(y-3)^2 = 16\)

So, you have found the equation of a circle.

Answer:

Both are correct.

Step-by-step explanation:

This is most probably a trick question because when you solve the mean and median of both you can clearly see that their answers are averages are correct, even the rounding of decimals.

Answer:

  Michael is wrong

Step-by-step explanation:

You want to know which student has misunderstood their grade computation, given the mean and median scores shown.

The mean of the test grades is their sum, divided by their number. The values shown for the mean grades are correct.

"Average" is another name for "mean." Thus the students' grade average will be the value of their mean grade, not their median grade.

Michael in incorrect in assuming that his median grade of 70% earns him a C in the class.

15=8x

Divide both sides by 8

x = 1.875 = 15/8

x ≈ 1.88

Answer:

x = -3.5

I don't think v is in the equation, correct me if I'm wrong though.

Step-by-step explanation:

r(x) = 5x - 3.5

r(x) = -21

Substitute:

-21 = 5x - 3.5

Add 3.5 on both sides to isolate the variable

-17.5 = 5x

Divide 5 on both sides

x = -3.5

Answer: $125

Step-by-step explanation:

1/80=x/10,000

10,000/80=125

Hope this helped!

Answer:125 yen

Step-by-step explanation:
Ratio and proportion

Ratio=1:80=x:10,000

x represents dollars which is unknown

1/80=x/10,000

Then you cross multiply

80x=10,000

80x/80=10,000/80

x=125

Therefore,$125 will give you 10,000yen

Answer: 6000 or 120

Step-by-step explanation:

P=$6,000

R=?

T=1 year

Answer:

The sample proportion is 0.253.

Step-by-step explanation:

We are given that a 90% confidence interval for a proportion is found to be (0.22, 0.28).

Firstly, as we know that the confidence interval for sample proportion is calculated as;

90% confidence interval = Sample proportion \(\pm\) Margin of Error

Here, let \(\hat p\) = sample proportion

Also, the level of significance = 1 - 0.90 = 0.10 or 10%

And, the critical value of z at 5% (two-sided) level of significance is 1.645.

So, 90% confidence interval =  \(\hat p \pm 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)

           (0.22 , 0.28)    =   \(\hat p \pm 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)

This means;  

          0.22  =  \(\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)  -------------- [Equation 1]

          0.28  =  \(\hat p + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)  -------------- [Equation 2]

From equation 1 and 2, we get;

           \(0.22 + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }= 0.28 - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)

           \(1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} } + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }= 0.28 -0.22\)

             \(2 \times 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} } =0.06\)

                 \(\sqrt{\frac{\hat p(1-\hat p)}{n} } =\frac{0.06}{2 \times 1.645}\)

                  \(\sqrt{\frac{\hat p(1-\hat p)}{n} } =0.02\)

Now, squaring both sides, we get;

                    \({\frac{\hat p(1-\hat p)}{n} } =0.0004\)

                      \(n ={\frac{\hat p(1-\hat p)}{0.0004} }\)

Now, putting value of n in equation 1, we get;

                    0.22  =  \(\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)  

                    0.22  =  \(\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{\hat p(1-\hat p)}\times 0.0004 }\)

                    0.22  =  \(\hat p - 1.645 \times \sqrt{ 0.0004 }\)

                    0.22  =  \(\hat p -( 1.645 \times 0.02)\)

                    0.22  =  \(\hat p -0.033\)

                      \(\hat p = 0.22 + 0.033\) = 0.253

Therefore, the sample proportion  \(\hat p\) is 0.253.
