mean=(a+b+c+d+e+f+g)/7

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm.

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

mean=[tex]\dfrac{(a+b+c+d+e+f+g)}{7}[/tex]

Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.

Step-by-step explanation:

soory i can't give an answer

The answer is: [tex]z_1-z_2[/tex]= 4-4([tex]\sqrt{3i}[/tex]-4i)

The correct option is: (D)

A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re(z), and 'b' is called the imaginary part Im(z).

Since we have given : [tex]z_1[/tex]==4-4[tex]\sqrt{3i}[/tex] and [tex]z_2[/tex]= -16i

The difference of z1 - z2 would be:

So,

[tex]z_1-z_2[/tex] = 4-4[tex]\sqrt{3i}[/tex] - (-16i)

[tex]z_1-z_2[/tex] =4-4[tex]\sqrt{3i}[/tex]+16i

[tex]z_1-z_2[/tex] =4-4([tex]\sqrt{3i}[/tex] -4i)

Hence, [tex]z_1-z_2[/tex]= 4-4([tex]\sqrt{3i}[/tex]-4i)

About 30-34 hours i estamate

Step-by-step explanation:

Alonso should work for 38 hours to earn $554.80.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Alonso earned $204.40 at his job when he worked for 14 hours.
Let Alonso per hour be x,
x = 204.40 / 14
x = 14.6

Now,
Alonso works for hours to earn $554.80,
= total pay/pay of an hour
= $554.80 / 14.6

= 38

Alonso should work for 38 hours to earn $554.80.

Thus, Alonso should work for 38 hours to earn $554.80.

(a) The differential equation is separable, so we separate the variables and integrate:

[tex](x+1)\dfrac{dy}{dx} = xy \implies \dfrac{dy}y = \dfrac x{x+1} \, dx = \left(1-\dfrac1{x+1}\right) \, dx[/tex]

[tex]\displaystyle \frac{dy}y = \int \left(1-\frac1{x+1}\right) \, dx[/tex]

[tex]\ln|y| = x - \ln|x+1| + C[/tex]

When x = 0, we have y = 2, so we solve for the constant C :

[tex]\ln|2| = 0 - \ln|0 + 1| + C \implies C = \ln(2)[/tex]

Then the particular solution to the DE is

[tex]\ln|y| = x - \ln|x+1| + \ln(2)[/tex]

We can go on to solve explicitly for y in terms of x :

[tex]e^{\ln|y|} = e^{x - \ln|x+1| + \ln(2)} \implies \boxed{y = \dfrac{2e^x}{x+1}}[/tex]

(b) The curves y = x² and y = 2x - x² intersect for

[tex]x^2 = 2x - x^2 \implies 2x^2 - 2x = 2x (x - 1) = 0 \implies x = 0 \text{ or } x = 1[/tex]

and the bounded region is the set

[tex]\left\{(x,y) ~:~ 0 \le x \le 1 \text{ and } x^2 \le y \le 2x - x^2\right\}[/tex]

The area of this region is

[tex]\displaystyle \int_0^1 ((2x-x^2)-x^2) \, dx = 2 \int_0^1 (x-x^2) \, dx = 2 \left(\frac{x^2}2 - \frac{x^3}3\right)\bigg|_0^1 = 2\left(\frac12 - \frac13\right) = \boxed{\frac13}[/tex]

6 × 384

6 × 4 = 24(carry the 2)

6 × 8 + 2 = 50(carry the 5)
6 × 3 + 5 = 23

Put it all together into one number

23 + 0 + 4 = 2,304

3,856 + 284

6 does not add to 4 so it's 0

5 + 8 = 14(carry the 1 and add 1)

8 cannot add onto 2 so use the one you borrowed and carry. = 1

3 + 1 = 4

Put it together

4 + 1 + 4 + 0 = 4,140

414,000

Simply add the two 0's in 100 to 4,140

414,000 ÷ 2,304

Turn 4,140 into the thousands place temporarily.

One gallon is equal to 4.546 liters and one mile is equal to 1.609 kilometers. Then the ratings in kilometers per liter will be 13.45.

Conversion means to convert the same thing into different units.
