Answer:

-36 ÷ -3

Step-by-step explanation:

Change in her school lunch account balance per lunch = -3

Total change in her school lunch balance last month = -36

Expression to show number of times Elena bought lunch last month = Total change in her school lunch balance last month ÷ Change in her school lunch account balance per lunch

= -36 ÷ -3

= -36/-3

= 12 times

Elena bought lunch 12 times last month

Answer:

0.105195x - 0.14156

Step-by-step explanation:

The relationship between heavy metal CD sales and size of teenage population is to be obtained. The attached table shows the result obtained from a regression analysis.

The dependent variable, which is the predicted value or variable, y = heavy metal yield

The Independent variable, predictor variable, x = heavy metal yield

Feommthe table ;

Coefficient of x = slope 0.105195

Intercept = - 0.14156

The general form of a simple linear regression model is :

y = mx + c

c = intercept ; m = slope

Therefore, we have the model :

y = 0.105195x - 0.14156

Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t  log(2)

divide by log 2

1.19264508=  10 /t

10(1.19264508)

Answer

$266.66

Step-by-step explanation:

We have here ,

We can use the formula of SI to calculate the SI . After adding it to principal we will get the amount .

⇒ SI = P × R × T / 100

⇒ SI = $ 200 × 16 × 10 / 12 × 100

⇒ SI = $ 26.66

Now Calculate amount as ,

⇒ A = SI + P

⇒ A = $ 200 + $ 26.66

⇒ A = $ 226.66

Given:

The figure of a right triangle.

To find:

The length of AB.

Solution:

In a right angle triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

Using this trigonometric ratio for the given triangle, we get

[tex]\cos A=\dfrac{AB}{AC}[/tex]

[tex]\cos (60^\circ)=\dfrac{AB}{10}[/tex]

[tex]\dfrac{1}{2}=\dfrac{AB}{10}[/tex]

[tex]\dfrac{1}{2}\times 10=AB[/tex]

[tex]5=AB[/tex]

Therefore, the length of AB is 5 units.

Answer:

Step-by-step explanation:

so you want to know the formula for the volume of a cylinder

volume (cylinder) = area of the circular base * height

2279.64 = area of a circle + height

area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]

they tell us the radius is 11 feet   so r = 11

circle = [tex]\pi[/tex][tex]11^{2}[/tex] = 38013271

2279.64 = 38013271 * height

2279.64 / 38013271 = height

5.996958 = height   in feet

Answer:

  8×10⁵ = 800,000

Step-by-step explanation:

The difference is ...

  (4.78×10⁶) -(3.98×10⁶) = 0.80×10⁶ = 8×10⁵

8×10⁵ = 800,000 more people attended at the largest extravaganza.

Your calculator (or a spreadsheet) can do the subtraction and display the number in whatever format you want.

Using the binomial distribution, it is found that:

a) The mean is of 0.36 and the standard deviation is of 0.58.

b) There is a 0.0036 = 0.36% probability that there are exactly three universal donors.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The values of the parameters are given as follows:

n = 6, p = 0.06.

Item a:

The mean is of 0.36 and the standard deviation is of 0.58.

Item b:

The probability is P(X = 3), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{6,3}.(0.06)^{3}.(0.94)^{3} = 0.0036[/tex]

There is a 0.0036 = 0.36% probability that there are exactly three universal donors.

Answer:

11

Step-by-step explanation:

The distance between them can be calculated using Distance Formula , the points here are (8,7) and (1,-2) . Using Distance Formula we have ,

⇒ D = √ [ (x_2 - x_1)² + (y_2 - y_1)² ]

⇒ D = √ [ (8-1)² + (7+2)² ]

⇒ D = √ [ 7² + 9² ]

⇒ D = √ [ 49 + 81 ]

⇒ D = √ 130

⇒ D = 11.401 units

Rounding off we have , 11.401 ≈ 11 units .

Answer:

48 yd²

Step-by-step explanation:

The shaded region is a trapezoid

Area of shaded region = area of the trapezoid

Area of trapezoid = ½(a + b)h

a = 6 yd

b = 10 yd

h = 15 - 9 = 6 yd

Area of trapezoid = ½(6 + 10)6

= ½(16)6

= 48 yd²

Area of the shaded region = 48 yd²
