Answer: X = 20

Step-by-step explanation:

7x - 99 = 2x + 1 --Take 2x from both sides

-2x -2x

5x - 99 = 1 -- add 99 to both

+99 +99

5x = 100 --Divide by 5

÷5 ÷5

x = 20

Use the equation and type the ordered-pairs. y = log 3 x {(1/3, a0), (1, a1), (3, a2), (9, a3), (27, a4), (81, a5)

vagabundo [1.1K]

Answer:

Considering the given equation $y = log_{3}x\\$

And the ordered pairs in the format $(x, y)$

I don't know if it is log of base 3 or 10, but I will assume it is 3.

For $(\frac{1}{3}, a_{0} )$

$x=\frac{1}{3}$

$y=a_{0}$

$y = log_{3}x\\y = log_{3}(\frac{1}{3} )\\y=-\log _3\left(3\right)\\y=-1$

So the ordered pair will be $(\frac{1}{3}, -1 )$

For $(1, a_{1} )$

$x=1$

$y=a_{1}$

$y = log_{3}x\\y = log_{3}1\\y = log_{3}(1)\\Note: \log _a(1)=0\\y = 0$

So the ordered pair will be $(1, 0 )$

For $(3, a_{2} )$

$x=3$

$y=a_{2}$

$y = log_{3}x\\y = log_{3}3\\y = 1$

So the ordered pair will be $(3, 1 )$

For $(9, a_{3} )$

$x=9$

$y=a_{3}$

$y = log_{3}x\\y = log_{3}9\\y=2\log _3\left(3\right)\\y=2$

So the ordered pair will be $(9, 2 )$

For $(27, a_{4} )$

$x=27$

$y=a_{4}$

$y = log_{3}x\\y = log_{3}27\\y=3\log _3\left(3\right)\\y=3$

So the ordered pair will be $(27, 3 )$

For $(81, a_{5} )$

$x=81$

$y=a_{5}$

$y = log_{3}x\\y = log_{3}81\\y=4\log _3\left(3\right)\\y=4$

So the ordered pair will be $(81, 4 )$

If the lowest value of a data set increases what happens to the standard deviation

lara [203]

Answer:

It becomes lower

Step-by-step explanation:

This is because as the lowest value becomes larger, <em>one of the values becomes closer to the mean</em>, and as more numbers are closer to the mean, the standard deviation becomes lower.

Help I'll give brainiest.

Tcecarenko [31]

Answer:

See missing answers bold

$20 original = $5 final paid as $15 was s/p before -10 was added

$30 original = $14 final price as $24 was s/p before -10 was added

$60 original = $35 final price as $45 was s/p before -10 was added

$92 original = $69 final price as $59 was s/p before -10 was added

Step-by-step explanation:

Ans in bold

A) = f(x) = 20(0.75) -10 = 15 - 10 = $5 = £5 final paid

B)= f(x) 30 (0.75) = 24 - 10 = 14 = $30 original price

C) = f(x) = 60(0.75) -10 = 45 -10 = $35 = $35 final price

D) = f(x) = 92 (75) = 69 -10 = $59 = $92 original price
