Answer:
10 +c=3
C=3-10
C=-7
.....
Answer:
c = -7
first, make the equation.
10 more than a number c is 3
the variable is c, according to the sentence.
c
"10 more than a number c"
c + 10
"10 more than a number c is 3 "
c + 10 = 3
now that you have your equation, time to solve it.
it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.
for example.
2 + 2 = 4
if you add 1 to both sides of the equation,
2 + 2 + 1 = 4 + 1
5 = 5
this is still true.
Solving the equation.c + 10 = 3
subtract 10 from both sides of the equation.
c + 10 - 10 = 3 - 10
c = 3 - 10
c = -7

the sum of two dice that are independently rolled is like the sum of two draws from the box containing six tickets labeled 1, 2, 3, 4, 5, 6. a student thinks taking one draw from the box with 11 tickets labeled 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 would give the same answers. do you agree? explain your reasoning.
The sum of two draws from a box containing 11 tickets labeled 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 is equivalent to the sum of two dice rolls, as the outcomes are not equally likely
What are dice rolls?
Dice rolls are a random event used in various games and activities. A dice typically has six sides, each side marked with a different number of , ranging from 1 to 6. To roll a dice, the player tosses it in the air, causing it to spin and land on a random side.
Dice rolls are often used in games of chance, such in role-playing games, where they are used to determine the outcome of actions or events. They are also used in probability theory, where the probability of a certain outcome can be calculated based on the number of sides on the dice and the number of times it is rolled.
The sum of two dice that are independently rolled and the sum of two draws from a box containing six tickets labeled 1, 2, 3, 4, 5, 6 are indeed equivalent. This is because there are 36 possible outcomes when rolling two dice, and each outcome is equally likely. The sum of the two dice can range from 2 (when both dice show a 1) to 12 (when both dice show a 6).
Similarly, when drawing two tickets from a box containing six tickets labeled 1, 2, 3, 4, 5, 6, there are 36 possible outcomes, with each outcome being equally likely. The sum of the two draws can range from 2 (when both draws yield a 1) to 12 (when both draws yield a 6).
However, if we use a box containing 11 tickets labeled 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, the outcomes will not be equally likely, and the sum of the two draws will not be the same as the sum of two dice rolls. For example, there is only one way to get a sum of 2 with two dice (rolling two 1s), but there are two ways to get a sum of 2 when drawing from the box (drawing a 1 and a 1 or drawing a 2 and a 0).
Therefore, we cannot say that the sum of two draws from a box containing 11 tickets labeled 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 is equivalent to the sum of two dice rolls, as the outcomes are not equally likely.

Find the critical value za/2 that corresponds to the confidence level 92%. Za/2 =
The critical value zα/2 for a level of confidence of 92% can be found as follows: In general, the confidence interval for the population mean is given by:\($$\large\bar x \pm z_{\frac{\alpha }{2}}\frac{\sigma }{\sqrt{n}}$$\) Where, \(\(\bar x\)\) is the sample meanσ is the population standard deviation (if known) or the sample standard deviation is the sample size\(\(z_{\frac{\alpha }{2}}\)\)is the critical value that corresponds to the level of confidence α.
We need to find\(\(z_{\frac{\alpha }{2}}\)\) for a 92% confidence interval. The area in the tail of the normal distribution beyond zα/2\(zα/2\) is equal to \((1 - α)/2\) . Thus, for a level of confidence of 92%, the area in the tail of the distribution beyond\(zα/2\)is\((1 - 0.92)/2 = 0.04/2 = 0.02\) .
Therefore, the critical value\(zα/2\) that corresponds to a 92% confidence interval is\(z0.04/2 = z0.02 = 1.75\) . Hence, we have\(:$$\large z_{\frac{\alpha }{2}}= z_{0.02} = 1.75$$\) Thus, the critical value \(zα/2\) that corresponds to a confidence level of 92% is 1.75.

B. 15.7 cm
OC. 31.4 cm
OD. 14.3 cm
The correct option is B. The length of arc AB of the circle C rounded to the nearest tenth is 15.7cm.
How to evaluate for the arc length AB of the circleWe shall use the formula:
arc length = (arc angle/360) × 2 × 22/7 × radius
where arc angle is measured in degrees and radius is the distance from the center of the circle to the point on the circle where the arc begins.
If BC = 10cm and is the radius, with the arc angle m ∠ACB = 90° then the arc length AB is derived as follows:
(90°/360°) × 2 × 22/7 × 10cm
90°/360° can be reduced to 1/4
1/4 × 2 × 22/7 × 10cm
By simplifying further, we have;
1 × 11/7 × 10cm
