I really need help with this guys
(p+8)^3

Answer:

2 cm

Step-by-step explanation:

As we know, the iqr is found by subtracting Q3-Q1. So that means we need to find them first. Finding the median will help us accomplish this task. So when writing out the numbers to solve it 81,82,83,83,84,84,84,85 because the amount of data points are an even number, we will have two data points which will help us solve our median which in this case is where the 83 and 84 meet. Our median is thus 83+84/2 which is 83.5. Now look on both sides of the two numbers which make up our median. On either side of the 2 data points needed for the median, the is another 3 data points. To find your q1 and q3, you need to find the median of these numbers. For Q1 look for the median between the numbers 81,82,83 and for Q3, look for the median in the numbers 84,84,85. So, knowing this information, our Q1 value is 82 and our Q3 value is 84. So..... input these into the equation we have up top which is Q3-Q1=IQR so...... 84-82=IQR, thus, our IQR is 2.

Answer: 25 , 10 years

Step-by-step explanation:

Suppose the present age of Artie and Carrie is x and y

According to the question, 5 years ago

[tex]\Rightarrow x-5=4(y-5)\\\Rightarrow x-4y=-15\quad \ldots(i)\\[/tex]

In five year time

[tex]\Rightarrow x+5=2(y+5)\\\Rightarrow x-2y=5\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

[tex]x=25,y=10[/tex]

The current age of Artie and Carrie is 25 and 10 years

B. Simple Random Sampling

Step-by-step explanation:

Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected

Answer:

Commission on car = $4,702.24

Step-by-step explanation:

Given:

Sales price of car = $29,389

Commission on sale of car = 16% = 0.16

Find:

Commission on car

Computation:

Commission on car = Sales price of car x Commission on sale of car

Commission on car = 29,389 x 16%

Commission on car = 29,389 X 0.16

Commission on car = $4,702.24

(5x6)x(3x2) = (30x6)= 180

Answer:

14 portion

Step-by-step explanation:

Given:

Total mass of potatoes = 49 pound

Mass of each small bag = 3.5 pound

Find:

Total number of bags

Computation:

Total number of bags = Total mass of potatoes / Mass of each small bag

Total number of bags = 49 / 3.5

Total number of bags = 14 bags

Total 14 portion can me made from big bag

Answer:

Step-by-step explanation:∠ MON= -45°→→ angle lies in fourth quadrant.

Where, MN represents the path of rock, which is a straight line.

Taking the Horizontal and vertical component of OM,to get the coordinate of point M

The coordinate of point M will be [1.25 cos (-45°), 1.25 sin(-45°)]=

Taking O as center and Coordinates of O as (0,0) and Coordinates of M as () we get the equation of line OM as

y= tan (315°)× x

As general form of equation of line passing through the origin will be,

y= m x, where m is angle made by line with positive direction of x axis.

m= (360-45)°= 315°

→→y=-x

→→  y +  x=0

equation of line perpendicular to OM will be

→→ x -  y + k=0

Since it passes through .

→→

So, equation of initial path of stone will be:

Answer:

x = 27

Step-by-step explanation:

Given

[tex]\sqrt{2x+10}[/tex] - 6 = 2 ( add 6 to both sides )

[tex]\sqrt{2x+10}[/tex] = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

Step-by-step explanation:

Answer:

141.94 cm³/s

Step-by-step explanation:

Since the volume of the tank V = πr²h, and both the height and radius of the tank change with time, we find the rate of change of the volume with time, dV/dt from

dV/dt = dV//dr × dr/dt + dV/dh × dh/dt

where dV/dr = 2πrh, dr/dt = + 0.2 cm/s (since the radius of the tank expands), dV/dh = πr² and dh/dt = -0.5 cm/s (since the height of the tank decreases)

So,

dV/dt = dV/dr × dr/dt + dV/dh × dh/dt

dV/dt =  2πrh ×  + 0.2 cm/s +  πr² ×  -0.5 cm/s

dV/dt =  0.4πrh cm/s -  0.5πr² cm/s

dV/dt =  πr(0.4h - 0.5r) cm/s

We now find the rate at which the volume is changing when r = 1.8 cm and h = 65 cm.

So,

dV/dt =  π(1.8 cm)(0.4 × 65 cm - 0.5 × 1.8 cm) cm/s

dV/dt =  π(1.8 cm)(26 cm - 0.9 cm) cm/s

dV/dt =  π(1.8 cm)(25.1 cm) cm/s

dV/dt =  π(45.18 cm²) cm/s

dV/dt = 141.94 cm³/s

I think you have to multiply them to get the answer $13.5

Answer:

2(x+10)

Step-by-step explanation:

Well since sum is addition and the number and 10 are the sum, let’s make the “number“ (x) and add em up. 10+x.

Now we gotta double that sum which is basically

2(10+x)

Answer:

5x² - 5x + 17

Step-by-step explanation:

(3x² + 7) + (2x² - 5x + 10)

Combine the like terms.

3x² + 2x² = 5x²

-5x does not have a like term, so there is no change.

7 + 10 = 17

Combine them, and the final equation is

5x² - 5x + 17.

Answer: 5x² - 5x + 17

Step-by-step explanation:

(3x^2+7)+(2x^2-5x+10)

3x^2 + 2x^2

-5x

7 + 10

5x^2 - 5x + 17
