Given:

A figure of a circle.

To find:

The value of x.

Solution:

Central angle theorem: According to this theorem, the central angle on an arc is twice of the subtended angle on that arc.

Using the central angle theorem, we get

$x=2\times 35^\circ$

$x=70^\circ$

Therefore, the value of x is 70 degrees.

Will a large-sample confidence interval be valid if the population from which the sample is taken is not normally distributed? e

Dovator [93]

A normal distribution is a type of continuous probability distribution for a real-valued random variable in statistics.

Yes, the large-sample confidence interval will be valid.

<h3>What is meant by normal distribution?</h3>

A normal distribution is a type of continuous probability distribution for a real-valued random variable in statistics.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far from the mean.

The confidence interval will be valid regardless of the shape of the population distribution as long as the sample is large enough to satisfy the central limit theorem.

<h3>What does a large sample confidence interval for a population mean?</h3>

A sample is considered large when n ≥ 30.

By 'valid', it means that the confidence interval procedure has a 95% chance of producing an interval that contains the population parameter.

Solve for x<br> And show work

klemol [59]

Answer:

x = -8

Step-by-step explanation:

1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.

2. Given the above information, that means x + 96 + 100 + x = 180.

3. (Solving for equation above)

Step 1: Simplify both sides of the equation.

$(x+x) + (96+100)=180$
$2x + 196 = 180$

Step 2: Subtract 196 from both sides.

$2x + 196 - 196 = 180 - 196$
$2x = -16$

Step 3: Divide both sides by 2.

$\frac{2x}{2} = \frac{-16}{2}$
$x = -8$

Step 4: Check if solution is correct.

$-8 + 96 + 100 - 8 = 180$
$88 + 100 - 8 = 180$
$188-8=180$
$180=180$

Therefore, x = -8.

At another school they sell a different brand of gift wrap which costs $2 per package and cards for $5 per package. Your friends

zhenek [66]

Hi there,

5x?=110 ?=22

how? 110/5=22

now 2x?=110

110/2=55 ?=55'

so we know now that people bought 22 packages with card and 55 w/th out cards!

so no we need to divide 695/both

695/5=139 packages with cards

695/2=347 packages without cards

SO

139 packages with card

347 packages without card

allsm [11]

The correct answer for the question that is being presented above is this one:

We want to pull 11 (this means not including 12) or less from the bag and there are 100 possibilities
= 11/100
So the probability is <span>11/100</span>
