Answer:

x = 70

Step-by-step explanation:

The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, then

x = \frac{1}{2} (80 + 60) = 0.5 × 140 = 70

Data set 1 : the mean is (1+2+4+4+5+5+6+7+9+9+9+11) / 12 = 72/12 = 6

the MAD is :
1 - 6 = -5....|-5| = 5
2 - 6 = -4....|-4| = 4
4 - 6 = -2...|-2| = 2
4 - 6 = -2...|-2| = 2
5 - 6 = -1...|-1| = 1
5 - 6 = -1...|-1| = 1
6 - 6 = 0 ...| 0| = 0
7 - 6 = 1....|1| = 1
9 - 6 = 3...|3| = 3
9 - 6 = 3...|3| = 3
9 - 6 = 3...|3| = 3
11 - 6 = 5...|5| = 5

(5+4+2+2+1+1+0+1+3+3+3+5) / 12 = 30/12 = 2.5 <== the MAD

2nd data set :
the mean is (1+3+4+6+6+6+7+9+9+10+10+13) / 12 = 84/12 = 7

mad is :
1 - 7 = -6...| -6| = 6
3 - 7 = -4...|-4| = 4
4 - 7 = -3...|-3| = 3
6 - 7 = -1...|-1| = 1
6 - 7 = -1..|-1| = 1
6 - 7 = -1..|-1| = 1
7 - 7 = 0...|0| = 0
9 - 7 = 2...|2| = 2
9 - 7 = 2...|2| = 2
10 - 7 = 3..|3| = 3
10 - 7 = 3...|3| = 3
13 - 7 = 6...|6| = 6

(6+4+3+1+1+1+0+2+2+3+3+6) / 12 = 32/12 = 2.67 <== the MAD

the difference of the means is 1. This value is less then half of the mean absolute deviation of either data set. <== ur answer

Given f(x) = 52x, evaluate f-1), f(o), and K2).<br><br> 01/25, 1, 625
lbvjy [14]

Answer:

f(-1) = \frac{5}{2}

f(0) = 5

f(2) = 20

Step-by-step explanation:

Given

f(x) = 5(2^x)

Required

Determine f(-1); f(0) and f(2)

Solving f(-1)

In this case, we simply take x as;

x = -1

Substitute -1 for x in f(x) = 5(2^x)

f(-1) = 5(2^{-1})

Apply law of indices

f(-1) = 5 * \frac{1}{2}

f(-1) = \frac{5}{2}

Solving f(0)

In this case, we simply take x as;

x = 0

Substitute 0 for x in f(x) = 5(2^x)

f(0) = 5(2^0)

f(0) = 5(1)

f(0) = 5

Solving f(2)

In this case, we simply take x as;

x = 2

Substitute 2 for x in f(x) = 5(2^x)

f(2) = 5(2^2)

f(2) = 5(4)

f(2) = 20

Express the following in scientific notation: 0.0000079
Law Incorporation [45]

Answer:

7.9 * 10 ^-6

Step-by-step explanation:

Move the decimal 6 places to the left so there is one number before the decimal

0.0000079

7.9

The exponent is -6  ( negative because we moved it to the left)

7.9 * 10 ^-6

Wang Hao wants to spend at most $15 on dairy products. Each liter of goat milk costs $2.40 and each liter of cow's milk costs $1
Mashutka [201]

Answer:

2.40g + 1.20c ≤15

Step-by-step explanation:

Each liter of goat milk costs $2.40 and each liter of cow's milk costs $1.20

Let g = liters of goats milk

c = liters of cows milk

What we are buying is the liters times the cost

2.40g + 1.20c

This must be less than or equal to 15 dollars

2.40g + 1.20c ≤15
