Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

Let's solve your equation step-by-step.

$\frac{1}{4} x^2+5=0$

For this equation: $a=0.25, b=0, c=5$

$0.25x^2 + 0x + 5 = 0$

Step 1: Use quadratic formula with $a=0.25, b=0, c=5.$

$x = \frac{-b ± \sqrt{b^2 - 4ac} }{2a}$

$x = \frac{-(0) ± \sqrt{(0)^2 -4 (0.25) (5) } }{2(0.25)}$

$x = \frac{0 ± \sqrt{-5} }{0.5}$

Answer : No Real Solutions.

Researchers collected data from 100 randomly chosen counties in Texas on pollution levels and asthma rates. Pollution levels wer

lesya692 [45]

Answer:

The answer is "3.14".

Step-by-step explanation:

The coefficient of pollution level is "b" and "a" intercept

$\to y=a+bx\\\\$

We must verify it.

$H_0 :\beta = 0\\\\H_a : \beta \neq 0\\\\$

$Beta \to b=1.76, SE=0.56 \ Estimate$

The statistics on tets are now provided

$\to t=\frac{b}{SE}=\frac{1.76}{0.56}=3.14$

Because statistics will be more than critical $(1.984)$ values, we thus reject $H_0$

the radius of a cylindrical construction pipe is 2.5 ft. if the pipe is 21 ft long, what is its volume? use the value 3.14 for p

pishuonlain [190]

Answer: The volume of the pipe is 412 cubic feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder = π x radius² x height (Length in this case)

Replacing with the values given:

V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet (rounded)

In conclusion, the volume of the pipe is 412 cubic feet

Feel free to ask for more if needed or if you did not understand something.
