4 0

Answer:

The first answer is 36 and the second is 80 because each pattern increases by one tile longer and wider so pattern 4 would be 4 by 4 so there would be 16 square tiles and 16 circular tiles and pattern 5 would have 25 square tiles and 20 circular tiles.

The average number of passes in a football game is right skewed with mean 75 and variance 961. If we sample 100 random games, wh

suter [353]

Answer:

0.0066

Step-by-step explanation:

Given that:

Mean $\mu$ = 75

Variance $\sigma^2 =961$

The standard deviation $\sigma = \sqrt{961} = 31$

The sample size n = 100

$\mu = \mu_{\overline x} = 75$

$\sigma _{\overline x} = \dfrac{\sigma }{\sqrt{n}}$

$\sigma _{\overline x} = \dfrac{31 }{\sqrt{100}}$

$\sigma _{\overline x} = \dfrac{31 }{10}}$

$\sigma _{\overline x} = 3.1$

$P(\overline x > 83.7) = 1 - P( \overline x < 83.7)$

$P(\overline x > 83.7) = 1 -P\bigg ( \dfrac{\overline x - \mu_{\overline x} }{\sigma _{\overline x}} < \dfrac{83.7 - 76}{3.1} \bigg)$

$P(\overline x > 83.7) = 1 -P\bigg ( Z< \dfrac{7.7}{3.1} \bigg)$

$P(\overline x > 83.7) = 1 -P ( Z< 2.48)$

Using the Z table;

P(x > 83.7) = 1 - 0.9934

P(x > 83.7) = 0.0066

Thus, probability = 0.0066

Enter the letter for the function graphed below. <br> A) y=3^sqrt x-3<br> B) y=3 sqrt x -3

Ira Lisetskai [31]

Answer: е) Step-by-step explanation: we know the coordinates of the points so we can easily determine which function this is To begin with, let's take any two points with an integer coordinates let these be two points with coordinates (1 ; 4) and (0 ; 3) Now let's check $a) \ \displaystyle\bf 4=\sqrt[3]{1-3} \ \ wrong$ and all other options except option e are incorrect because $\displaystyle\ e) \sqrt[3]{1} +3=4 \ \ right$
