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.

Using rules, we can simplify expressions with exponents, factorize, or expand them.  [tex]2 x \sqrt{10 x}-2 x \sqrt{5}.$[/tex] Thus option D is correct,

We can simplify the expression using the rules of exponents and algebraic manipulation.

[tex]$\sqrt{5 x}\left(\sqrt{8 x^2}-2 \sqrt{x}\right) = \sqrt{5 x} \cdot \sqrt{8 x^2} - 2\sqrt{5 x} \cdot \sqrt{x}$[/tex]

[tex]$= \sqrt{(5x)(8x^2)} - 2\sqrt{(5x)(x)}$[/tex]

[tex]$= \sqrt{40x^3} - 2\sqrt{5x^2}$[/tex]

[tex]$= \sqrt{4x^2 \cdot 10x} - 2x\sqrt{5}$[/tex]

[tex]$= 2x\sqrt{10x} - 2x\sqrt{5}$[/tex]

Hence, the simplified product where [tex]$x \geq 0: \sqrt{5 x}\left(\sqrt{8 x^2}-2 \sqrt{x}\right)$ is $2 x \sqrt{10 x}-2 x \sqrt{5}.$[/tex]

Therefore, Using rules, we can simplify expressions with exponents, factorize, or expand them.  the correct option is $(D) [tex]2 x \sqrt{10 x}-2 x \sqrt{5}.$[/tex]

Answer:

First rectangular solid and second Rectangular solid

1. Bases are in the form of square having same dimensions

2. Height of first rectangular solid=2 ×Height of second rectangular solid

The true statements are

A) The bases are congruent.→The meaning of term congruent is that , the two bases are in the shape of square having same dimensions.

(B) No, The solids are not similar.as ratio of side lengths in not same in each case , because the ratio of heights of two solid is equal to .

(D) Volume of first solid = x *x*2 H=2 x²H

Volume of second solid = x*x*H=x²H

Ratio of volumes =2:1

So, option (D) is true.

(E) Surface area of first solid =2[x*x+x*2 H+2 H*x]

=2[x²+4 H*x]=2 *x*[x+4* H]

Surface area of second solid = 2[x*x+x* H+ H*x]=2[x²+2 H*x]=2* x*[x+ 2*H]

Option A, D, E are correct about two solids.

Answer:

Long side of the rectangle: 11cm

Shorter side of the rectangle: 7cm

Step-by-step explanation:

36cm divided by 4 = 9

9-2=7

take that two and add it to the other two nines

9+2=11

The required length of the longer sides of rectangle is 10cm.

The perimeter of the rectangle is 36 centimeters,
length = 2+ width

rectangle is four sided polygon whose opposites sides are equal and has angle of 90° between its sides.

Perimeter = 2 length x 2 width
36 = 2(2+width) x 2width
36= 4 (1+width)
width = 8
length= 2+width
length = 2+ 8
length = 10 centimeters

Thus, The required length of the longer sides of rectangle is 10cm.

Answer: Mary is 36 and her son is 12; in 12 years her son will be 24 and she will be 48

Step-by-step explanation:

Answer:

Mary's age = 36

Son's age = 12

Step-by-step explanation:

Let x be age of Mary and y be age of her son.

According to question,

x = 3y...........(1)

And,

x + 12 = 2(y + 12)

x + 12 = 2y + 24

Replacing value of x from (1),

3y + 12 = 2y + 24

3y - 2y = 24 - 12

y = 12

And x = 3 x 12 = 36

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)

Given that :

Number of green gum drops = 30

Number of Blue gum drops = 1

Total number of gum drops :

(Number of blue + number of green gum drops)

(30 + 1) = 31

Probability = Required outcome / Total possible outcomes

P(green gum drops) = number of green drops / total number of gum drops

P(green gum drops) = 30 / 31 = 0.967 ≈ 0.97
