Answer:

y intercept = 5

Step-by-step explanation:

f(x)=5•(1/6)^x

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)^0      

= 5* 1     = 5

The y intercept is 5

If the question is

f(x)=5•(1/6)x

although I have never seen the question written this way

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)0      

= 5* 0     = 0

The y intercept is 0

Answer:

B.    1

Step-by-step explanation:

The y-intercept occurs at x = 0

therefor the applicable function is

f(x) = -x + 1

at x=0

f(0) = -0 + 1

f(0) = 1

Hello there! Mizuki here to help!

The correct answer will be:

Fred is going to spend $1380.41

Step-by-step explanation:

The whole work I did:

500 x 0.3 = 150

617 x 0.59 = 364.03

379 x 0.98 = 371.42

116 x 4.25 = 493

2 x 0.98 = 1.96

150 + 364.03 + 371.42 + 493 + 1.96 = 1380.41

Answer:

A) x¯ = 134.5

s² = 276.7 is the same for both formulas

s = 16.634

B) At 68.26%, we have (117.866, 151.134)

At 95.44%, we have (101.232, 167.768)

At 99.73%, we have (84.598, 184.402)

C) Yes, it will be considered high because 190 doesn't fall between any of the 3 tolerance intervals gotten in B above.

Step-by-step explanation:

A) The random 6 entertainment expenses are;

$157, $132, $109, $145, $125, $139

We want to find x¯ which is the mean.

Thus;

x¯ = (Σx)/n

x¯ = (157 + 132 + 109 + 145 + 125 + 139)/6

x¯ = 134.5

s² is the variance and can be calculated from 2 different formulas which are;

s² = (Σ(x - x¯)²)/n

Or s² = ((Σx²) - (Σx)²/n)/(n - 1)

For the first formula, when calculated we have;

s² = [(157−134.5)² + (132−134.5)² +(109−134.5)² + (145−134.5)² +(125−134.5)² + (139−134.5)²]/6

s² = 276.7

For the second formula;

(Σx²) = (157)² + (132)² + (109)² + (145)² +(125)² + (139)² = 109925

(Σx) = (157 + 132 + 109 + 145 + 125 + 139) = 807

Thus;

s² = (109925 - (807²/6))/(6 - 1)

s² = 276.7

So both formulas gave the same result of s²

s = √s² = √276.7

s = 16.634

B) from the empirical rule, 68% of the data will fall within one standard deviation while 95% of the data will fall within two standard deviations, and then 99.7% of the data will fall within three standard deviations from the mean.

Now, 68.26% will correspond to 1 standard deviation from the means and the tolerance level Formula here is;

x¯ ± s = 134.5 ± 16.634

This gives; (117.866, 151.134)

95.44% will correspond to within 2 standard deviations and the formula here is;

x¯ ± 2s = 134.5 ± 2(16.634)

>> (101.232, 167.768)

99.73% will correspond to within 3 standard deviations and the formula here is;

x¯ ± 3s = 134.5 ± 3(16.634)

>> (84.598, 184.402)

C) Yes it would be considered high because it doesn't fall between any of the 3 intervals in B above.

Answer:

  8)  a. chord

  9)  b. radius

Step-by-step explanation:

8) Of the items listed, only a chord and a diameter are segments. A diameter is a chord, so of the two appropriate choices, we prefer the more general answer "chord" .

__

9) Of the segments listed, only the radius has one end point at the center of the circle.

Answer:

1/14

Step-by-step explanation:

The sectors labeled are B, Y, G, C, P, F, O, V, M, A, D, E, H, and R.

Total number of sectors = 14.

When Victoria spins the spinner 18 times, and it stops at the letter B 10 times.

When Victoria spins the spinner  the theoretical probability that this time it will stop at the letter B = Favourable  outcomes ÷total number of outcomes.

Favourable outcomes =1 and Total number of outcomes = 14.

Hence Theoretical Probability = 1 over 14.

Answer:

$89.93

Step-by-step explanation:

Set up an equation:

Variable x = original price

40/100 = 35.97/x

Cross multiply

40 × x = 100 × 35.97

40x = 3597

Divide both sides by 40

x = 89.925

Round to the nearest cent:

5 rounds up so:

89.93

Check your work (use the original number instead of the rounded number to be more exact):

89.925 × 40%

Convert the percentage into a decimal to multiply:

89.925 × 0.40

Step-by-step explanation:

The equivalent value of the logarithmic equation is x = 7/3

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the logarithmic equation be represented as A

Now , the value of A is

A = log ( 14/3 ) + log ( 11/5 ) - log ( 22/5 )

On simplifying , we get

From the properties of logarithm , we get

log A + log B = log AB

log A − log B = log A/B

So , A = log (14/3) + log (11/5) - log (22/5) = log [(14/3) × (11/5) / (22/5)]

A = log [(14/3) × (11/5) × (5/22)]

A = log ( 14/3 /2 )

A = log ( 7/3 )

Hence , the logarithmic equation is solved

Divide both sides by 4.

y = -2.5x + 5

Answer:

The predicted score for the dependent variable will be of 198,454.4.

Step-by-step explanation:

Equation of a regression line:

The equation of a regression line has the following format:

[tex]y = ax + b[/tex]

In which a is the slope and b is the intercept. x is the independent variable while y is the dependent variable.

A certain regression line equation has the slope equal to 326.07 and an intercept that is equal to 8.19.

So [tex]y = 326.07x + 8.19[/tex]

What will be the predicted score for the dependent variable if the independent variable is 608.6?

y when x = 608.6. So

[tex]y = 326.07*608.6 + 8.19 = 198454.4[/tex]

The predicted score for the dependent variable will be of 198,454.4.
