Write the equation of the graph below

Mathematics
1 answer:
Olenka [21]3 years ago
7 0

Answer:

Step-by-step explanation:

This is a parabola with a vertex at h = 4 and k = 5; the graph goes through the coordinate x = 6 and y = 6. We will use those 4 values to fill in the equation:

y=a(x-h)^2+k and this will allow us to solve for the value of a:

6=a(6-4)^2+5 and

6=a(2)^2+5 and

6 = 4a + 5 and

1 = 4a so

a=\frac{1}{4} and the equation is

y=\frac{1}{4}(x-4)^2+5

In January 2002, two students made worldwide headlines by spinning a Belgian euro 250 times and getting 140 heads—that’s 56%. Th
natita [175]

Answer with explanation:

The 90% confidence interval (51%, 61%) for proportion means that the proportion of getting heads lie in it.

Given : Total number of times coin is tossed = 250

Number of times they got head =140

The probability of getting a head = 0.56

The confidence interval for proportion is given by :-

p\pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given significance level : \alpha=1-0.90=0.1

Critical value : z_{\alpha/2}=z_{0.05}=\pm1.645

Now, the 90​% confidence interval for proportion will be :-

0.56\pm (1.645)\sqrt{\dfrac{0.56(1-0.56)}{250}}\approx0.56\pm 0.0516\\\\=(0.56-0.0516,0.56+0.0516)=(0.5084,\ 0.6116)\approx(51\%,\ 61\%)

Hence, the given confidence interval is correct.
