Find the value of c to the nearest tenth

PLZ HELP NEED THIS REAL FAST DIS QUESTION HARD ILL GIVE 10 POINTS Jaquenline and her four friends went to the the fair. JaQuenli

ki77a [65]

Answer:

d. 5(x + 6) = 47.50

Step-by-step explanation:

First, determine the number of girls; (4 friends + Jacquenline) making a total of 5 girls.

If a ticket costs $6, then the the 5 girls' tickets would cost= 5*6

Also, if a funnel cake costs $x , then 5 girls' cakes would cost= 5* x

Total cost of funnel cake and entry tickets = $47.50

Now make the above three into an equation;

(5*x) + (5*6) = 47.50

5 is the common number on the left side so it becomes;

5( x +6) =47.50

Help plz???? never learned this

stira [4]

suppelementary angles are angles that add to 180

remember that a straight line is 180 degrees so some angles that are supplementary are 1 and 2, 5 and 6, 1 and 5, 6 and 2, 3 and 7, 4 and 8, 7 and 8, 3 and 4

vertical angles are across from each other when 2 lines cross, they are like 5 and 2, 6 and 1, 7 and 4, 8 and 3

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard d

MatroZZZ [7]

The correct option is ''The value of 135 because it is not greater than 136.5 values is outside the 99% confidence interval for the population mean''

<h2>Given that,</h2>

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard deviation of 34.

Which of the following values is outside the 99% confidence interval for the population mean?

<h3>According to the question,</h3>

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard deviation of 34.

Sample space n = 85,

Mean = 146

And standard deviation = 34

Then, The standard error of the sample is,

$= \dfrac{\sigma}{n}\\\\= \dfrac{34}{\sqrt{85}}\\\\= \dfrac{34}{9.21}\\\\= 3.6$

Then, z-critical value for 99% is 2.58,

Margin of error = ±9.515

Confidence interval for lower bound is,

= 146 - 9.515 = 136.485

And confidence interval upper bound is,

= 146 + 9.515 = 155.515

Here, 135 is less than the lower bound,

Therefore, 135 does not lie within a 99% confidence interval.

For more details about Lower bound refer to the link given below.

How heavy is 24 carat gold?

fomenos

<span>24k gold is also called pure gold or 100 per cent gold. This means that all 24 parts in the gold are all pure gold without traces of any other metals. It is known to be 99.9 per cent pure and takes on a distinct bright yellow color. There is no higher form of gold than 24K and you must be aware of this before you go to a dealer who might tell you that they’re selling you 25K or 26K gold. Since this is the purest form of gold, it is naturally more expensive than 22K or 18K gold. However, this type of gold is lesser in density as compared to gold of a lower karatage which makes it soft and pliable. Hence, it is not suited for regular forms of jewellery. Coins and bars are mostly bought of 24K gold purity. 24K gold is also used in electronics and medical devices such as those used for children suffering from ear infections who are fitted with gold tympanostomy tubes that are known to improve aeration of the middle ear.</span>
