Answer:

108.88

Step-by-step explanation:

Given that:

Equation of Regression line obtained for couple's IQ:

y=9.88+0.9x

x represents the IQ score of the husband

The best predicted IQ of wife Given that husband's IQ is 110

y = 9.88 + 0.9(110)

y = 9.88 + 99

y = 108.88

Step-by-step explanation:

Answer:

The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.

Step-by-step explanation:

Avogadro's Number or Avogadro's Constant is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and it applies to any substance.

Then you can apply the following rule of three: if 6.023*10²³ molecules are present in 1 mole, 3.13*10²³ molecules are present in how many moles?

[tex]moles=\frac{3.13*10^{23}molecules*1 mole }{6.023*10^{23}molecules}[/tex]

moles= 0.52

Since the molar mass of carbon dioxide is 44 g / mole, then the following rule of three can be applied: if there are 44 g in 1 mole, how much mass is there in 0.52 moles?

[tex]mass=\frac{0.52 moles*44 g}{1 mole}[/tex]

mass= 22.88 g

The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.

Answer:

12 sweets

Step-by-step explanation:

2:5:3.

caroline gets 12 so multiply the ratio by 6.

12:30:18

Krutika has 30, Natasha has 18.

30-18=12

so 12 sweets

Answer:

1.5 meters

Step-by-step explanation:

they first move forward 2 meters and then move backwards 1 meter (1 meter from their starting point, and then they move forward 0.5 meters. So the displacement of the dancers from their starting point is 1.5 meters.

0 + 2 = 2

2 - 1 =  1

1 + 0.5 = 1.5

hope this helps!

I think it's 8 this is my opinion btw

Answer:

x is less than oe equal to 12

Answer:

x ≤ 15

Step-by-step explanation:

7x - 6 ≤ 3x + 54

Subtract 3x from both sides;

4x - 6 ≤ 54

Add 6 to both sides;

4x ≤ 60

Divide both sides by 4;

x ≤ 15

y=2/3 orange for each friend (decimal: 0.6667 rounded to 4d. p)

PREMISES

y=the fraction of 2 oranges that each of 3 friends shares equally

CALCULATIONS

To distribute 2 oranges equally between 3 friends requires that the oranges be sliced proportionately equal to the number of friends which is 3

So, then,

y=

Each friend receives 1/3 of each of 2 oranges making 2/3 orange for each friend.

If y=2/3 orange, then the equations

3*2/3 orange=2 oranges

6/3 oranges=2 oranges and

2 oranges=2 oranges prove the solution y=2/3 orange to the fraction of 2 oranges shared by each of 3 friends

Answer:

[tex]\dfrac{9}{20}\ \text{pounds}[/tex]

Step-by-step explanation:

Given that,

Maggi buys 3/4 pound of blueberries

He uses 3/5 of them to make a smoothie.

We need to find how many pounds of blueberries Maggi use to make the smoothie. It means we need to find 3/5 of 3/4. So,

[tex]x=\dfrac{3}{4}\times \dfrac{3}{5}\\\\=\dfrac{9}{20}\ \text{pounds}[/tex]

So, he will use [tex]\dfrac{9}{20}\ \text{pounds}[/tex] of blueberries to make a smoothie.

Answer: 9/20

Step-by-step explanation: Maggi buys 3/4 pound of blueberries

He uses 3/5 of them to make a smoothie.

We need to find how many pounds of blueberries Maggi use to make the smoothie. It means we need to find 3/5 of 3/4. So,

So, he will use of blueberries to make a smoothie.

Step-by-step explanation:

20x-25+3x-1=20

20x+3x=20+25+1

23x=46

X=2

Answer:

x=2

Step-by-step explanation:

5(4x-5)+3x-1=20 (given)

20x - 25 + 3x -1 = 20 (distribute)

23x -26 = 20 (combine like terms)

23x = 46 (add)

x=2 (division)

Answer:

The solutions to the system of the equations are:

[tex]y=1,\:x=3[/tex]

Step-by-step explanation:

Given the equations

[tex]y=\frac{2}{3}x-1;\:y=-x+4[/tex]

solving the system of equation

[tex]\begin{bmatrix}y=\frac{2}{3}x-1\\ y=-x+4\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-\frac{2}{3}x=-1\\ y+x=4\end{bmatrix}[/tex]

[tex]y+x=4[/tex]

[tex]-[/tex]

[tex]\underline{y-\frac{2}{3}x=-1}[/tex]

[tex]\frac{5}{3}x=5[/tex]

[tex]\begin{bmatrix}y-\frac{2}{3}x=-1\\ \frac{5}{3}x=5\end{bmatrix}[/tex]

solving for x

[tex]\frac{5}{3}x=5[/tex]

[tex]5x=15[/tex]

Divide both sides by 15

[tex]\frac{5x}{5}=\frac{15}{5}[/tex]

[tex]x=3[/tex]

[tex]\mathrm{For\:}y-\frac{2}{3}x=-1\mathrm{\:plug\:in\:}x=3[/tex]

[tex]y-\frac{2}{3}\cdot \:3=-1[/tex]

[tex]y-2=-1[/tex]

Add 2 to both sides

[tex]y-2+2=-1+2[/tex]

[tex]y=1[/tex]

Therefore, the solutions to the system of the equations are:

[tex]y=1,\:x=3[/tex]

Answer:

1750

Step-by-step explanation:

2000-1750=250

250x7=1750

To find the equation of the parabola, first let's write the parent function,

y = a(x-h)^2+k. Ok, now we need to find the vertex and plug it in. Remember, (h,k). When we look at the problem the vertex is (0,4). Therefore we write it as y = a(x-0)^2 +4 or y = ax^2 + 4. Now we need to look to see if it was stretched or compressed. Keep in mind that on a normal parabola, if you move over 1 you go up one. If you move over 2 you go up four. If you move over 3, you go up 9. In this problem, you move over 1, you go up 1. If you move over 2, you go up 4. If you move over 3, you go up 9. From this information, we see that there is no stretch or compression. Therefore the equation of the graph shown is:

y= x^2 +4

Answer:

76/100

Step-by-step explanation: 76 is in the hundreds place

Given :

A pre-image arrow pointing east is rotated 135° clockwise.

To Find :

In which direction is the image arrow point.

Solution :

90° clockwise shift make it south.

Now, remaining angle for rotation ( 135 - 90 )° = 45°.

So, direction of moving 45° more clockwise makes it 45° west of south or 45° south of west.

Hence, this is the required solution.

Answer:

Its a inequality
