Can some please help me?? It’s do today also can you guys explain how to do it because it’s still More questions and I actually
Genrish500 [490]

Answer:

-3

Step-by-step explanation:

Slope of a line is "rise over run".  Pick two points on the line.  For example, (0,4) and (1,1).  As we move from the first point to the second, we move down 3 units and right 1 unit.  So the slope is -3/1 = -3.

Here's an algebraic approach.  If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:

m = (y₂ − y₁) / (x₂ − x₁)

Plugging in our two points:

m = (1 − 4) / (1 − 0)

m = -3

There are 60 people in a choir
Aloiza [94]

Answer:

The value of n is 2.

Step-by-step explanation:

The total number of people in the choir = 60

Number of  women in the choir = 30

Let the number of men in the choir be represented by x, so that;

Number of women = 3x

So that;

3x = 30

x = \frac{30}{3}

 = 10

The number of men in the choir is 10.

the number of children in the choir: the number of men in the choir = n:1

number of children in the choir = 60 - (number of women + number of men)

                                                    = 60 - 40

                                                    = 20

number of children in the choir = 20

Thus,

the number of children in the choir: the number of men in the choir = 20:10

                                                            = 2:1

The value of n is 2.

In January 2002, two students made worldwide headlines by spinning a Belgian euro 250 times and getting 140 heads—that’s 56%. Th
natita [175]

Answer with explanation:

The 90% confidence interval (51%, 61%) for proportion means that the proportion of getting heads lie in it.

Given : Total number of times coin is tossed = 250

Number of times they got head =140

The probability of getting a head = 0.56

The confidence interval for proportion is given by :-

p\pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given significance level : \alpha=1-0.90=0.1

Critical value : z_{\alpha/2}=z_{0.05}=\pm1.645

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

0.56\pm (1.645)\sqrt{\dfrac{0.56(1-0.56)}{250}}\approx0.56\pm 0.0516\\\\=(0.56-0.0516,0.56+0.0516)=(0.5084,\ 0.6116)\approx(51\%,\ 61\%)

Hence, the given confidence interval is correct.
