Answer:

7x + 4y = 17

Step-by-step explanation:

Answer:

x = -1

Step-by-step explanation:

(6 - 3) / (-1 - -1) = 3/0 so there is no slope

so the equation is x = -1

Answer:

[tex]\theta=270^\circ[/tex]

Step-by-step explanation:

Given Equation and Parameters

[tex]sin^2\theta-4sin\theta-5=0,\: 0^\circ\leq\theta\leq 360^\circ[/tex]

Calculation

Let [tex]u=sin\theta[/tex], thus:

[tex]u^2-4u-5=0\\\\(u+1)(u-5)=0\\\\u=-1,\: u=5[/tex]

[tex]sin\theta=-1\\\\\theta=270^\circ[/tex]

[tex]sin\theta=5\\\\\theta=unde fined[/tex]

Conclusion

[tex]\theta=270^\circ[/tex]

Answer:

Step-by-step explanation:

x + y = 4 ............. (1)

x = y - 16 ............ (2)

(2) -------> (1)

( y - 16 ) + y = 4

2y = 20

y = 10

x = - 6 The smaller number

There are 720 different ways to arrange the books.

Here we know that there are a total of 7 books, 3 of math and 4 of sciences.

We know that the 3 math books must be together, so first let's analyze this element.

The number of permutations of these 3 books is 3! = 3*2*1 = 6

Now we have 5 elements, 4 books of science and a "group of math books."

So there are 5 positions in which the group of math books can be, and for the four science books we have 4! = 4*3*2*1 = 24 permutations.

The total number of different combinations is given by the product of the numbers we found above:

combinations  = (permutations of math)*(possible positions of math)*(permutations of science).

Combinations = 6*5*24 = 720

48 + 36 written as a product of two factors gives; 12 × 7

We are given the function;

48 + 36

Let us pick the largest common factor of both numbers which is 12 and so we will factorize to have;

12*4 + 12*3

⇒ 12(4 + 3)

⇒ 12 * 7

Thus, the correct answer is 12 * 7

Anasia is a basketball player who regularly shoots sets of 2 free throws. The required standard deviation is 0.65

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

Anasia is a basketball player who regularly shoots sets of 2 free throws. Suppose that each shot has a probability of 0.7, point, and 7 being made, and the results of the shots are independent.

[tex]e \times P(X=x) \\=0\times 0.09+1\times0.42+2\times0.49\\=0.49+0.98\\\\1.4[/tex]

Now,

[tex]E(X^2) = 0\times0.009 +1^2 \times0.42 +2\times0.42\\\\= 0.42+ 1.96\\\\=2.38[/tex]

we can calculate the standard deviation by variance

[tex]\sigma^2 = E(X^2) - (E(X))^2\\\\\sigma^2 =2.38 - 1.4^2\\\\\sigma^2 =0.42\\\\\sigma = 0.65[/tex]

The required standard deviation is 0.65
