hello! :) have a good day!

1). 24

2). 27

3). 5

PICTURE 1:

The answer is 24: (13 7/10) Rounded To The Nearest Whole Number is: (14)

[tex]13 \frac{7}{10} = 14[/tex]

AND,

(10 1/8) Rounded To The Nearest Whole Number is: (10)

[tex]10 \frac{1}{8} = 10[/tex]

So, 14 + 10 = 24

PICTURE 2:

The answer is 5: (8 1/5) Rounded To The Nearest Whole Number is: (8)

[tex]8 \frac{1}{5} = 8[/tex]

AND,

(2 7/8) Rounded To The Nearest Whole Number is: (3)

[tex]2 \frac{7}{8} = 3[/tex]

So, 8 - 3 = 5

PICTURE 3:

The answer is 27: (58 5/12) Rounded To The Nearest Whole Number is: (58)

[tex]58 \frac{5}{12} = 58[/tex]

AND,

(30 5/7) Rounded To The Nearest Whole Number is: (31)

[tex]30 \frac{5}{7} = 31[/tex]

So, 58 - 31 = 27

Answer:

I love math anyways

the ans is in the picture and the steps hope it helps :D hehe

(hope it helps can i plz have brainlist it will make my day :D hehe)

Step-by-step explanation:

1+3/8=(8+3)/8=11/8 used per day. 5+1/2=(10+1)/2=11/2 available.

(11/2)/(11/8)=(11/2)(8/11)=88/22=4

Answer:

a) The minimum sample size is 601.

b) The minimum sample size is 2401.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

For this problem, we have that:

We dont know the true proportion, so we use [tex]\pi = 0.5[/tex], which is when we are are going to need the largest sample size.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

a. If a 95% confidence interval with a margin of error of no more than 0.04 is desired, give a close estimate of the minimum sample size that will guarantee that the desired margin of error is achieved. (Remember to round up any result, if necessary.)

This is n for which M = 0.04. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96*0.5[/tex]

[tex]\sqrt{n} = \frac{1.96*0.5}{0.04}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.04})^2[/tex]

[tex]n = 600.25[/tex]

Rounding up

The minimum sample size is 601.

b. If a 95% confidence interval with a margin of error of no more than 0.02 is desired, give a close estimate of the minimum sample size necessary to achieve the desired margin of error.

Now we want n for which M = 0.02. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.02 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.02\sqrt{n} = 1.96*0.5[/tex]

[tex]\sqrt{n} = \frac{1.96*0.5}{0.02}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.02})^2[/tex]

[tex]n = 2401[/tex]

The minimum sample size is 2401.

Answer:

log(41)/log(7) OR 1.90839852...

Answer:

full arrow going left from 46

Step-by-step explanation:

Inequalities are used to represent unequal expressions.

The inequality is: [tex]h \le 46[/tex]

The height (h) is said to be no greater than 46 inches.

The text "no greater than" means less than or equal to.

In inequalities, less than or equal to is represented with <=

So, the inequality is:

[tex]h \le 46[/tex]

See attachment for the graph of the inequality.

Given:

The polynomial is

[tex]p(x)=x^3-2x^2+2x[/tex]

To find:

The real and complex zeros of the equation.

Solution:

We have,

[tex]p(x)=x^3-2x^2+2x[/tex]

For zeros, p(x)=0.

[tex]x^3-2x^2+2x=0[/tex]

[tex]x(x^2-2x+2)=0[/tex]

[tex]x(x^2-2x+2)=0[/tex]

[tex]x=0\text{ and }x^2-2x+2=0[/tex]

The real value of x is 0. The equation [tex]x^2-2x+2=0[/tex] will give complex roots. Here, a=1, b=-2 and c=2.

Using quadratic formula, we get

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(1)(2)}}{2(1)}[/tex]

[tex]x=\dfrac{2\pm \sqrt{4-8}}{2}[/tex]

[tex]x=\dfrac{2\pm \sqrt{-4}}{2}[/tex]

On further simplification, we get

[tex]x=\dfrac{2\pm \sqrt{-1}\sqrt{4}}{2}[/tex]

[tex]x=\dfrac{2\pm 2i}{2}[/tex]

[tex]x=\dfrac{2(1\pm i)}{2}[/tex]

[tex]x=1\pm i[/tex]

Therefore, the real zero is 0 and the complex zeros are 1+i and 1-i.
