Answer:

k = -4

Step-by-step explanation:

Applying the Distributive Property of Multiplication, we get

-3k + 15 = 27, which simplifies to -3k = 12. Then k must be

k = -12/3, or k = -4

For this case we must resolve the following expression: $log_ {0.5} (16)$

We have to:

$log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}$

The base change rule can be used if a and b are greater than 1 and are not equal to x.

We substitute the values in the base change formula, using $b = 10$

$\frac {log (16)} {log (0.5)} = - 4$

Suppose the null hypothesis is not rejected. State the conclusion based on the results of the test. Three years ago, the mean p

Likurg_2 [28]

Answer:

A. There is not sufficient evidence to conclude that the mean price of a single-family home has decreased

Step-by-step explanation:

To study : Whether the mean price of single family home has decreased or not -

Null Hypothesis [H0] = There is no change in mean price of single family home

Alternate Hypothesis [H1] = There is change (decrease) in mean price of single family home

If the null hypothesis is not rejected, it implies that 'there is no change in mean price of single family home' has been statistically accepted.

So, it states that - There is not sufficient evidence to conclude that the mean price of a single-family home has decreased

A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line? Help me please

joja [24]

Step-by-step explanation:

If it's a straight line the use formula

$y = mx + c$

m= gradient of line

c = y-intercept

we know that y-intercept is 4 so coordinate is

(0,4)

Equation also passes (2,10)

Use both coordinate to find gradient

m= vertical distance / horizontal distance

= (10-4) / (2-0)

= 3

y = 3x + 4
