What is 4708.06 rounded up to the nearest thousandths?

Answers

are you missing a number? cause you can’t round when you don’t even have thousandths

Answer:

4708.060

Step-by-step explanation:

The third place after the decimal is the thousands place, so there is nothing to change considering we do not know anything after the six. If a number after the number after six was 5 or higher, it would be 4708.007 :)

$1,451.02 _____ $1,541.02

Answers

Answer:

The second number ($1,541.02) is greater

Step-by-step explanation:

In the 100s place of the second number is a 5 and in the first a 4

Even though they have the same 1000s number 500 is larger that 400

I believe your question is referring to which is greater-than, less-than, or if it's equal-to?

If so, then: $1,451.02 < $1,541.02

just divide the price by the amount of oz. I don't have a calculator but that's what you do. Just round according to money.

Answer:

1) [tex]\huge\boxed{\sf 5.7}[/tex]

2) [tex]\huge\boxed{6.4}[/tex]

Step-by-step explanation:

74 oz = $ 4.24

74 oz = 4.25 * 100 cents

74 oz = 425 cents

Divide bot sides by 74

1 oz = 425 / 74 ¢ / oz

1 oz = 5.7 ¢ / oz

[tex]\rule[225]{225}{2}[/tex]

42 oz. = $2.69

42 oz = 2.69 * 100 cents

42 oz = 269 cents

1 oz = 269 / 42 cents

1 oz = 6.4 ¢ / oz

[tex]\rule[225]{225}{2}[/tex]

Jemima receives £5 pocket money
she spends £1.75 on a magazine and 80p on a drink
a)what fraction of the pocket money is spent
b)what fraction of the pocket money does she have left

Answers

Answer:

51% of the money was spent, that is, 51/100. In conclusion, Jemina still has 49/100 of the money available.

Step-by-step explanation:

Since Jemima received $ 5 in pocket money, and spent $ 1.75 on a magazine and $ 0.80 on a drink, to determine the proportion of money he spent and the proportion he has left, the following calculation must be performed:

5 - (1.75 + 0.80) = X

5 - 2.55 = X

2.45 = X

5 = 100

2.55 = X

(2.55 x 100) / 5 = X

255/5 = X

51 = X

Therefore, 51% of the money was spent, that is, 51/100. In conclusion, Jemina still has 49/100 of the money available.

A student polls his school to see if students in the school district are for or against the new legislation regarding school uniforms. She surveys 600 students and finds that 480 are against the new legislation.

Required:
a. Compute a 90% confidence interval for the true percent of students who are against the new legislation and interpret the confidence interval.
b. In a sample of 300 students, 68% said they own an iPod and a smart phone. Compute a 97% confidence interval for the true percent of students who own an iPod and a smartphone.

Answers

Solution :

68 % of the students owns iPod and a smart phone. So

p' = 0.68

q' = 1'

   = 1 - 0.68

   = 0.32

Since CL = 0.97, we know that [tex]$\alpha = 1 - 0.97 = 0.03 $[/tex]

The area to the left of [tex]$z_{0.015}$[/tex] is 0.015 and the area to the right of  [tex]$z_{0.015}$[/tex]  is [tex]$1 - 0.015 = 0.985 $[/tex]

Thus using [tex]$TI \ 83, 83+ \ or \ 84+$[/tex] calculator function [tex]$\text{InvNorm} (0.985, 0.1), z_{0.015} = 2.17$[/tex]

[tex]$\text{EBP} = z_{\alpha / 2} \times \left( \sqrt{\frac{p'q'}{n}}\right) $[/tex]

[tex]$\text{EBP} = 1.645 \times \sqrt{\frac{0.68 \times 0.32}{300}} $[/tex]

       = 0.0269

Therefore, we are ninety seven percent confident that a true proportion of all the students who has iPod as well as a smart phone is between the 0.6531 and 0.7069

a). (0.7731, 0.8269); We estimated that with 90% confidence, the true percentage of all the students in district who are against a new legislation is between 77.31% and 82.69%.

b). Now,

Press the 'STAT' and then arrow over to perform TEST.

Now arrow down to the A:1 - PropZint and then place Enter.

Arrow a down x and then enter the 300 x 0.68

Similarly arrow  a down to given n and then enter the 300

Now arrow down to the C-level and the enter the 0.97

Arrow a down for calculating and press the enter button.

The confidence interval is (0.6531, 0.7069)

a). (0.7731, 0.8269); We estimated that with 90% confidence, the true percentage of all the students in district who are against a new legislation is between 77.31% and 82.69%.

Hypotenuse : Not given

Opposite : 47

Adjacent : BC

Angle ( θ) = 61°

Using SOHCAHTOA

[tex]Tan\: \theta = \frac{Opposite}{Adjacent} \\\\Tan \: 61 = \frac{47}{BC} \\\\1.804 = \frac{47}{BC}\\\\Cross\:Multiply\\1.804BC= 47\\\\Divide\:both\:sides\:by\:1.8 \\\\\frac{1.804BC}{1.804} = \frac{47}{1.804} \\\\BC= 26.05[/tex]
