For the function Y=5x, what would happen if the value 5 was changed to 3

Mathematics
1 answer:
Daniel [21]4 years ago
4 0

Answer:

y = 3 * x

Step-by-step explanation:

We have the function y = 5 * x, they ask us what would happen if we change the 5 by the 3. thus:

y = 3 * x

the constant that accompanies x in this case is an increase or slope constant, that is, now x will not increase by a ratio of 5, but by a ratio of 3. For example:

If x were worth 10

the value before was 50 and now it will be 30.

I do not increase 5 times but 3 times.

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k. (1 point) 92 fix)
rewona [7]

Answer:

3

Step-by-step explanation:

g(x) = f(x) + k, is true for all values of x.

At x = 0, f(x) = 2

At x = 0, g(x) = 5

Therefore, at x = 0

=> g(x) = f(x) + k

=> 5 = 2 + k

=> 3 = k

Since, the given relation is true for all real values of x, k is independent of x. Thus k = 3, for every value of x

suppose a sample of 1305 tenth graders is drawn. Of the students sampled, 1044 read above the eighth grade level. Using the data
Inessa05 [86]

Answer: (0.771,\ 0.829)

Step-by-step explanation:

Given : Significance level : \alpha: 1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

Sample size : n=1305

The proportion of tenth graders read above the eighth grade level. =p=\dfrac{1044}{1305}=0.8

The confidence interval for population proportion is given by :-

p\pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}\\\\=0.8\pm(2.576)\sqrt{\dfrac{0.8(1-0.8)}{1305}}\\\\\approx0.8\pm0.029\\\\=(0.771,\ 0.829)

Hence, the 99% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level is (0.771,0.829) .
