Answer:

3

Step-by-step explanation:

f(x)=a*b^x - is a formula of exponential function

As we know the point (x=0; y=3) lies at the function's  graph.

So we have to put in formula f(x)=a*b^x   x=0  f(x)=y=3

3=a*b^0   (b^0=1) => 3=a*1 => 3=a

The circumference of one coin is 8.03cm. The circumference of another coin is 0.33cm smaller. A.) what is the first step to find
Burka [1]

Answer:

Diameter of the smaller coin = 2.46 cm

Step-by-step explanation:

Circumference of a coin = 2πr

Circumference of coin A = 8.03 cm

Circumference of coin B = 8.03 cm - 0.33 cm

A.) what is the first step to find the diameter of the smaller coin?

Find the circumference of coin B

Circumference of coin B = 8.03 cm - 0.33 cm

= 7.7 cm

B.) Find the diameter of the smaller coin.

Circumference of a coin = 2πr

7.7 = 2 × 3.14 * r

7.7 = 6.28r

r = 7.7 / 6.28

r = 1.23 cm

Diameter = 2r

= 2 * 1.23 cm

= 2.46 cm

Diameter of the smaller coin = 2.46 cm

HACTEHA [7]

Answer:

R^2 = r^2 = 0.445^2= 0.198

B. The coefficient of determination is 0.1980, 19.8​% of the variation is explained by the linear​ correlation, and 80.2​% is explained by other factors.

Step-by-step explanation:

Previous concepts

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.  

Solution to the problem

In order to calculate the correlation coefficient we can use this formula:  

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}  

On this case we got that r =0.445

The determinaton coefficient is just:

R^2 = r^2 = 0.445^2= 0.198

And we can put it on % and we got 19.8%. And represent the variation explained by a linear model. The best option on this case would be:

B. The coefficient of determination is 0.1980, 19.8​% of the variation is explained by the linear​ correlation, and 80.2​% is explained by other factors.

Since the explained variation is 19.8% and the remain 100-19.8= 80.2% is explained by other factors.

Thepotemich [5.8K]

Answer:

Step-by-step explanation:

Garrett achieves a field goal is independent of each kick.  Hence X no of kicks is binomial with p = 0.83, and q =0.17

No of trials 3

Hence X can take values as 0 ,1,2,3 and

P(X=r) = 4Cr(0.83)^r (0.17)^{4-r}

, r=0,1,2,3

Using the above we obtain prob distribution as

X         0                  1           2            3                

P(X)   0.0049   0.0720   0.3513   0.5718

P(X>=2) =P(X=2,3,4) =0.9231

-----------------------------------------

2) Z value for company A =\frac{260-272}{5.4} =-2.22

Z value for company B = (260-249)/3.8 =2.89

From z value probablility is more for company A as

P(Z>-2.22) >P(Z>2.89)
