Answer: y=mx+b = y=30(15)+1

Explanation: the slope is 30 because that's how many minutes it will take her to write each page and x will be the amount of pages she is doing as b is the 1 hour she spent doing her outline. (Hope this helped if I'm incorrect I'm so sorry, I'm tired)

Answer:

8.5 hours

Step-by-step explanation:

30 mins per page ( 15 )

so, 30 × 15 = 450

each hour is 60 minutes so 450 ÷ 60 = 7.5

then add the 1 hour that she already took to write the outline, so 8.5 hrs

Which quadratic function has a y-intercept of 4?

8090 [49]

Answer:

This tells us that the vertex is at (−2, 9) and the equation of the axis of symmetry is x = −2. To find the x-intercepts, we put y = 0 to obtain

(x + 2)2 − 9 = 0

(x + 2)2 = 9

x + 2 = 3 or x + 2 = −3

x = 1 or x = −5.

Step-by-step explanation:

Image result for Which quadratic function has a y-intercept of 4? y=x2−2x+4 y=x2+2x+9 y=−x2+3x y=x2+13x+12

The standard form of a quadratic equation is written as y=ax2+bx+c, where x and y are variables and a, b, and c are known constants. To find the y-intercept from a quadratic equation, substitute 0 as the value for x and solve. The y-intercept is always equal to the value of c in the equation.

x^2 - x/5 + 2 = 0

Subtract 2 from both sides.

x^2 - x/5 = -2

Multiply all terms by 5.

5x^2 - x = -10

Add 10 to both sides.

5x^2 - x + 10 = 0

We can now apply the quadratic formula:

$-b ± \frac{\sqrt{b^2 - 4ac} }{2a}$

1 ± (√ 1 - 200) / 10

1 ± √-199 / 10

1 ± i√199 / 10

<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>

Does consuming beer attract mosquitoes? A study done in Burkino Faso, Africa, about the spread of malaria investigated the conne

Pachacha [2.7K]

Answer:

Take u1 = average number of mosquitoes attracted after drinking beer

u2 = average number of mosquitoes attracted after drinking water

a) The null and alternative hypotheses:

H0 : u1 = u2

H1 : u1 > u2

b) i) The average number of mosquitoes per volunteer before drinking (beer group) :

$x'1 = \frac{x_1}{n} = \frac{434}{25} = 17.36$

Sample mean for mosquitoes attracted before consumption for beer group is 17.36

The average number of mosquitoes per volunteer before drinking (water group) :

$x'2 = \frac{x_2}{n} = \frac{337}{18} = 18.72$

Sample mean for mosquitoes attracted before consumption for water group is 18.72

The two means are different.

The difference in the two means are as a result of random choice.

c) i) The average number of mosquitoes per volunteer after drinking (beer group) :

$x'1 = \frac{x_1}{n} = \frac{590}{25} = 23.60$

Sample mean for mosquitoes attracted after consumption for beer group is 23.60

ii) The average number of mosquitoes per volunteer after drinking (water group) :

$x'2 = \frac{x_2}{n} = \frac{345}{18} = 19.17$

Sample mean for mosquitoes attracted after consumption for water group is 19.17

The two sample means are different.

This difference here is likely not to be as a result of random choice, because the mean difference here is greater than the mean difference before consumption.

d) A statistically significant difference provides evidence that beer consumption increases mosquito attraction, as the average number of mosquitoes attracted when drinking beer is higher than the mean number of mosquitoes attracted when drinking water.
