Answer:

$\frac{3}{35}$

$\frac{5}{7}$

Step-by-step explanation:

$\frac{3}{35} (7)=\frac{(3)(7)}{35} =\frac{21}{35} =\frac{3}{5}$

$\frac{5}{7} (7)=\frac{(5)(7)}{7} =\frac{35}{7} =5$

According to a Field Poll conducted February 8 – 17, 2005, 79% of California adults (actual results are 400 out of 506 surveyed)

Jobisdone [24]

Answer: (0.760, 0.820)

Step-by-step explanation:

Let p be the population proportion of all adults feel that "education and our schools" is one of the top issues facing California.

Given : 79% (actual results are 400 out of 506 surveyed) of California adults feel that "education and our schools" is one of the top issues facing California.

i.e.Sample size : n= 506

Sample proportion : $\hat{p}=0.79$

Critical value for 90% confidence interval ( Using z-value table) :

$z=1.645$

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

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

i.e. $0.79\pm (1.645)\sqrt{\dfrac{0.79(1-0.79)}{506}}$

i.e. $0.79\pm (1.645)(0.0181)$

$\approx0.79\pm 0.030=(0.79-0.030,\ 0.79+0.030)\\\\=(0.760,\ 0.820)$

Hence, the 90% confidence interval for the population proportion= (0.760, 0.820)

The function f(x) = 7x + 1 is transformed to function g through a horizontal compression by a factor of 1/3. What is the equatio

Iteru [2.4K]

Answer:

The answer is "3".

Step-by-step explanation:

If the compression factor of 3 is modified, the k value is 3 For a function f(x) the horizontal extending or compression is provided by g = f (bx)

Here b is constant. Where b is constant.

If b> 0, the function graph is condensed. The fact that perhaps the function is transformed by an encoding factor of 3 is given in the question.

$\to f(x)=7^x+1\\\\\to g=f(b(x))$
