Answer:

64 pounds of the $8.10 Mexican Shade Grown

36 pounds of the $14.10 Tanzanian

Step-by-step explanation:

8.1x + 14.1(100 - x) = 10.26(100)

Distribute

8.1x + 1410 - 14.1x = 1026

Combine like terms

1410 - 6x = 1026

Subtract 1410 from both sides

-6x = -384

Divide both sides by -6

x = 64 pounds of the $8.10

100 - x = 36 pounds of the $14.10

Answer:

x = 5.3

Step-by-step explanation:

Reference angle (θ) = 24°

Opposite side to the reference angle = x

Adjacent side = 12

Apply TOA, which is:

Tan θ = Opp/Adj

Plug in the values

Tan 24° = x/12

12*Tan 24° = x

5.34274422 = x

x = 5.3 (approximated to one decimal place)

An angle of depression is measured from the horizon downwards and an angle of elevation is measured from the horizon upwards.

When solving for the sides or angles of a right triangle you can use trigonometry. The sine of an angle is found by the ratio of the opposite side and the hypotenuse. The cosine of an angle is found by the ratio of the adjacent side and the hypotenuse. The tangent of an angle is found by the ratio of the opposite side and the adjacent side.

The opposite side is always the leg opposite the angle that you are using. The adjacent side is the leg that forms one of the sides of the angle you are talking about and the hypotenuse is always across from the right angle.

If you know two lengths you can find the third leg length by using the Pythagorean Theorem.

Answer:

obtuse

Step-by-step explanation:

A circle is 360 degrees

Divide by 3

360/3 =120

This is greater than 90 and less than 180 so it is obtuse

The probability the spy is able to unlock the tablet on his first try is P = 1/362880

Given that,

Camila sets up a passcode on her tablet, which allows only nine-digit codes.

And, A spy sneaks a look at Camila's tablet and sees her fingerprints on the screen over nine numbers.

Hence,  the total amount of different sequences that can be built using 9 digits is:

9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 362,880

Therefore, the probability the spy is able to unlock the tablet on his first try is,

P = 1/362880

Given:

The mean and the median of the monthly sales are 130,000 AED and 170,000 AED respectively.

To find:

The distribution of the monthly sales.

Solution:

We know that,

For symmetrical distribution, mean is equal to median.

For positively skewed distribution, mean is greater than median.

For negatively skewed distribution, mean is less than median.

We have,

Mean of the monthly sales =  130,000 AED

Median of the monthly sales = 170,000 AED

Here, Mean is less than the median because 130,000 < 170,000.

Therefore, the distribution is negatively skewed. Hence, the correct option is D.

I think it is 65 because we can divide it by 5

Answer:

i think there is only one multiple which is 65

Answer:

-4

Step-by-step explanation:

60 + x + 124 = 180 degree (being linear pair)

x + 184 = 180

x = 180 - 184

x = -4

Answer:

x+124=180(linear pair angle)

x=56

Answer:

pls complete your question. what exactly are we supposed to calculate?

Answer: Hello your question is incomplete below is the missing part of the question

The Bureau of the Census reports that the median family income for all families in the United States during the year 2003 was $43,318. That is, half of all American families had incomes  exceeding this amount, and half had incomes equal to or below this amount. Suppose that four  families are surveyed and that each one reveals whether its income exceeded $43,318 in 2003.

answer :

P(A) = 11 / 16

P(B)  = 3/8

and P(C) = 1/4

Step-by-step explanation:

Making use of the given interpretation for the median we can assign probabilities to simple events as

P(A) = | A | / | sample space |

where | A | = 11

sample space = 16

P(A) = 11 / 16

∴ P(B) = 6/16 = 3/8

and P(C) = 4/16 = 1/4

Answer:

g(x) = 2x + 1

Step-by-step explanation:

f(x)= 3x - 5 when it is translated 6 units up

Translating a function a units is adding a to the function. So

[tex]3x - 5 + 6 = 3x + 1[/tex]

Horizontal stretch by a factor of 3/2.

This means that [tex]g(x) = f(\frac{2x}{3})[/tex], that is. So

[tex]g(x) = 3(\frac{2x}{3}) + 1 = 2x + 1[/tex]

Then

g(x) = 2x + 1

Answer:

B. (1 ± sqrt(33)) / 4

Step-by-step explanation:

the 2 solutions for a quadratic equation

ax² + bx + c = 0

are defined as

x = (-b ± sqrt(b² - 4ac)) / 2a

in our example here we have

a = -2

b = 1

c = 4

=>

x = (-1 ± sqrt(1 + 32)) / -4 = (1 ± sqrt(33)) / 4

as we can easily divide top and bottom by -1 to turn the -1 and -4 into positive numbers, and the second top part, the square root, is a ± factor anyway. just withing the sign dues not change the fact that is is still a ± factor (both signs apply).

and now it is clear, it has to be option B.

the others disqualify because they have either no division by any form of 4, or the "1" and the "4" have different signs. but our equation shows they need to have equal signs (either both negative or both positive).

-Chetan K

Answer:

2396

Step-by-step explanation:

Let the diameter = d

Let the height = h

Formula

Metric Tons = k * d^4 / h^2

Solution

Metric Tons = 64

d = 2

h = 9

k = ?

(You can't do the second part by not using a ratio unless you  put k in and solve for it)

64 = 2^4 k / 9^2

64 = 8 *k / 81

64 * 81 / 8 = k

5184 / 8 = k

k = 648

Solve for the second example

Metric Tons = d^4 * k / h^2

Metric Tons = ?

d = 5

h = 13

k = 648

Metric Tons = 5^4 * 648 / 13^2

Metric Tons = 625 * 648 / 169

Metric Tons = 2396 rounded.

Answer:
