Through: (-5, -5), slope=2/5

kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

$y = mx + b$

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: $m = \frac {2} {5}$

Thus, the equation is of the form:

$y = \frac {2} {5} x + b$

We substitute the given point and find "b":

$-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3$

Finally, the equation is:

$y = \frac {2} {5} x-3$

Answer:

$y = \frac {2} {5} x-3$

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. A survey

marta [7]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Sample size = 865 = n

Number of voters favor approval of an issue before the legislature = 408 = x

So, $\hat{p}=\dfrac{x}{n}=\dfrac{408}{865}=0.4716$

At 95% confidence level of significance, z = 1.96

So, confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{p(1-p)}{n}}}\\=0.4716\pm 1.96\times \sqrt{\dfrac{0.4716\times (1-0.4716)}{865}}}\\\\=0.4716\pm 0.00082222\\\\=(0.4716-0.00082222..,0.4716+0.00082222...)\\\\=(0.471,0.472)$

Hence, option 'c' is correct.

Can y’all help me w this asap ?

Semmy [17]

Answer:

1) 512

2) 27

3) 216

4) 8

5) 343

6) 729

Step-by-step explanation:

1)(8^4)^3/4 = 8^3 [using the power of power rule]

=8*8*8

= 512

2) The second can be written as (81)^3/4

81 = 3^4

Therefore, (3^4)^3/4 = 3^3

= 27

3) 1296 = 6^4

Therefore, (1296)^3/4 = (6^4)^3/4

= 6^3

= 216

4) 16^3/4 = (2^4)^3/4

= 2^3

= 8

5) 2401 = 7^4

The expression can be written as (2401)^3/4

= (7^4)^3/4

= 7^3

= 343

6) 6561 = 9^4

The given expression can be written as (6561)^3/4

= (9^4)^3/4

= 9^3

= 729

Hope you will understand the concept.

Thank you.
