what is 2 X (6+ 2 + 8) -4

Answer:

I don't know the answer to this but

Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

Answer:

0.35 pounds in each cheesecake

Step-by-step explanation:

Number of individual blueberry cheesecakes = 15

Pounds of blueberries = 5 1/4 pounds

How many pounds of blueberries will be in each cheesecake if 5 1/4 pounds of blueberries are divided equally among them?

= 5 1/4 ÷ 15

= 21/4 ÷ 15

= 21/4 × 1/15

= (21*1)/(4*15)

= 21/60 pounds

Equivalent to 0.35 pounds in each cheesecake

Answer: Answer: $0.25

Step-by-step explanation:

Let x be the total money was in her wallet and m be the cost of each petunia,

From the given table , the money left in wallet after purchasing 2 petunia =$6.50

Then we have the following equation: 6.50 = x - 2m - - - - - ( 1 ) Also, the money left in wallet after purchasing 8 petunia =$5 Then, we have 5 = x - 8m - - - - - - - - - ( 2 ) Subtracting (2) from (1) , we get 6.50 - 5 = -2m - (8m) then -2m + 8m = 1.50 then we 6m = 1.50. m = 1.50/6 = 0.25 hope this helped.

Answer:

Squared differences between actual and predicted y

Step-by-step explanation:

The least squares regression method used in predictive modeling for linear regression models produces a best fit line which will minimize the square of the mean difference between the actual and projected or predicted values of the dependent, y variable. Hence, the when the sum of the squared value of the difference between the actual and predicted values (residual) are taken, the fit which gives the minimum sum of squared value is the best fit line upon which the estimated regression equation is based.

The true statement is that the estimated regression equation by least squares method minimizes the sum of the (c) Squared differences between actual and predicted y.

In regression, the least square method is used to estimate quantities.

This is done in order to minimize the sum of the squares of the differences between the observed values and the estimated values.

In this case, the observed value and the estimated values represent the actual and predicted y

Hence, the true statement is that the estimated regression equation by least squares method minimizes the sum of the (c)

Answer:

1. 363 to 2

2. 363:2

3. 363/2

Step-by-step explanation:

1. First of all, there are 365 days in a year.

* Note that the question says there are only 2 days where sports aren't played.

2. As said in the question there are 3 ways to write a ratio: a to b; a : b; a/b. Now, let's think that what are a and b in this scenario? a= says without games= 2; and b= days in a year= 365.

3. Now fill in the variables with the numbers for each form of a ratio.

a. 363 to 2

b. 363:2

c. 363/2

Step-by-step explanation:

Fraction is the representation of the parts of a whole number. The amount of cake ate by Norma in the lunch is 9/32 parts.

Total cake left over by the Norma after the party is 3/8.

Total cake she ate for the lunch is 3/4.

The value of the whole cake is given in the fraction parts. To solve this the fraction should be understood.

Fraction is the representation of the parts of a whole number.

As the one whole of cake was there earlier. The 3/8 part of the cake is,

[tex]=\dfrac{3}{8}[/tex]

As she ate the 3/4 part of the left over cake in the lunch. Suppose the part of cake she ate is x. Therefore the part of cake she ate at lunch is,

[tex]x=\dfrac{3}{8} \times\dfrac{3}{4}[/tex]

[tex]x=\dfrac{9}{32}[/tex]

Hence, the amount of cake ate by Norma in the lunch is 9/32 parts.

Answer:

Gavin is correct

Step-by-step explanation:

Since the problem is using a denominator of 10, I will convert 1 (1 representing the full length of the board before being sawed) to a fraction over 10

1 = 10/10

Subtract everything Gavin sawed off from the board

10/10 - 2/10 - 5/10 - 1/10

Only subtract the numerators; the denominators will stay the same

8/10 - 5/10 - 1/10

3/10 - 1/10

2/10

Gavin says he has 2/10 of the board left to use

Since we concluded we still have 2/10, he is correct

Answer:

Step-by-step explanation:

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

The area of the triangle.

= 1/2 x base x height

The area of the triangle is 105760 cm².

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

In ΔVWX.

w = 680 cm

∠X=80°

∠V=32°

This means,

∠W + ∠X + ∠V = 180

∠W = 180 - 112

∠W = 68°

This means,

68° = 680

1° = 10

Now,

∠X=80°

x = 800 cm

∠V=32°

v = 320 cm

Now,

           V

        /   |   \

(x)   /     |     \  (w)

   /        |        \

W         M        X

          (v)

680² = VM² + (320/2)²

462400 = VM² + 25600

VM² = 436800

VM = 661 cm

Thus,

The area of the triangle.

= 1/2 x base x height

= 1/2 x 320 x 661

= 160 x 661

= 105760 cm²
