Since Flying Falcon cost($8) is cheaper than Flying Bat($12), then the minimum possible cost each day would be the maximum possible Flying Falcon produced.
The maximum flying falcon produces is 60/day. Then, the amount of flying bat produced would be:

total= falcon + bat
70= 60+bat
bat= 70-60= 10

The minimum possible cost: falcon * falcon_cost + bat * bat_cost = 60*$8 + 10*$12 = $480+$120= $600

I need helppppp........

grin007 [14]

Answer:

Step-by-step explanation:

To do this, you need to complete the square.

$y=-2x^2-8x-13 \\\\y=-2(x^2+4x)-13 \\\\y=-2(x^2+4x+4)+8-13 \\\\y=-2(x+2)^2-5$

Therefore, the correct answer is choice B. Hope this helps!

A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado l

lisov135 [29]

Answer:

The null and alternative hypothesis are:

$H_0:\mu =2.6\\H_a:\mu >2.6$

There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles

Step-by-step explanation:

Consider the provided information.

The claim that the mean tornado length is greater than 2.6 miles.

If there is no statistical significance in the test then it is know as the null which is denoted by $H_0$ , otherwise it is known as alternative hypothesis which denoted by $H_a$ .

Therefore, the required null and alternative hypothesis are:

$H_0:\mu =2.6\\H_a:\mu >2.6$

significance level α =0.05

From the given table the test statistic T=2.230166

P-value is 0.0131

0.0131<0.05

P value is less than the significance level, so reject the null hypothesis.

There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
