How do you go from Vertex To standard Form?

Lynna [10]

The vertex form:

$y=a(x-h)^2+k$

The standard form:

$y=ax^2+bx+c$

$y=a(x-h)^2+k\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\y=a(x^2+2xh+h^2)+k\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\y=ax^2+2ahx+ah^2+k$

Jane is is charge of making a banner for the basketball game this Saturday. She measures how long the banner is before painting

RSB [31]

Answer:

The measurement which Jane finds to be 10 meters is the length of the banner.

Step-by-step explanation:

The measurement of 10 meters which Jane found after measuring how long the banner is before painting is the LENGTH of the banner.

This is clear from the unit of what she finds (meters). It only indicates the measurement of one part of the banner, even though a banner has two parts, the length and width.

It is possible to find the AREA, or PERIMETER, or LENGTH.

But what she finds is the LENGTH of the banner. If it was Area or Perimeter, the unit would have been square meters.

In a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man cl

Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Given that in a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less.

The sample size n = 80

no of wells less than 100 feet deep=27

Sample proportion = $\frac{27}{80} =0.3375$

a) Create hypotheses as

$H_0: p = 0.30\\H_a: p >0.30\\$

(Right tailed test)

p difference $= 0.3375-0.30 = 0.0375$

Std error of p = $\sqrt{\frac{0.3(0.7)}{80} } =0.0512$

b) Assumptions: Each trial is independent and np and nq >5

c) Z test can be used.

Z= p diff/std error = $\frac{0.0375}{0.0512} =0.73$

p value = 0.233

d) p value is the probability for which null hypothesis is false.

e) Conclusion: Since p >0.05 we accept null hypothesis

there is no statistical evidence which support the claim that more than 30% are drilled.
