if hxa =rgi,

then;

rgi =hxa

Step-by-step explanation:

Symmetric property of equality states

if x = y

then

y = x

As per the statement:

If $hxa =rgi$

by symmetric property of equality;

$rgi=hxa$

Therefore, symmetric property of equality is illustrated by the following statement.

a random sample of 130 students is chosen from a population of 4,500 students. if the mean iq in the sample is 120 with a standard deviation of 5, what is the 99% confidence interval for the students' mean iq score? answers given below: 118.87−121.13 107.12−132.88 125−135 115−125

Answers

Answer with explanation:

Total Sample Size = 4,500 Students

Sample Chosen(n) = 130 students

Mean IQ of the Sample, $\bar{X} = 120$

Standard Deviation, $\sigma=5$

To Calculate 99% confidence interval for the students' mean IQ score, we will calculate,

$Z_(99 percent)=2.58$

Formula for Confidence Interval

$=\bar{X} \pm Z_(99 percent)* (\sigma)/(√(n))\n\n=120 \pm 2.58 * (5)/(√(130))\n\n=120 \pm (12.9)/(11.401)\n\n =120 \pm 1.1314\n\n=120 \pm 1.13$

The Value of Confidence interval will lie between

⇒ 120 - 1.13 to 120 +1.13

⇒118.87 to 121.13

Option A: 118.87−121.13

$C.I.=120 \pm z_( \alpha /2) ( \sigma )/( √(n) ) \n =120 \pm 2.58 * (5)/( √(130) ) \n =120 \pm 1.13 \n =118.87 - 121.13$

An angle is formed by the junction of two rays.
a. True
b. False

Answers

The most probable and most likely answer to this problem of true or false would be true.

An angle is formed by the junction of two rays. Usually, when two rays are in junction, two angles are formed. Either the formed angle is an acute angle, obtuse angle, or a right angle. The other angle that comes with the formed angle mentioned earlier would be a reflex angle. When two rays form just a line, the angle formed would be just one which is a complete rotation, thus the angle would be a 360 angle.

Akiba Ellis deposits the following in her checking account: 6 five-dollar bills, 5 two dollar bills, 12 one dollar bills, 9 half dollars, 6 quarters, 42 dimes, 10 nickels, 15 pennies, and a check for $97.23. what is her total deposit?

Answers

Answer:

$106.08

Step-by-step explanation:

Given:

6x $5.00

5x $2.00

12x $1.00

9x= 0.50

6x25 cent

42x10 cent

10x5 cent

15=15cent

$97.23

----------------------------------------------------------------------------------

6 five dollar bill is $30.00

so 5 two dollar bill is $10.00

12 one dollar bills is $12.00

9 half dollar bill mean 0.50 cent since it Half and that would make $4.50

6 quarter so 6x25 which equal $1.50

42 dimes and dimes =10 cent so 42x10 which equal $4.20

10 nickels and nickels = 5 cent so 10x5=0.50

15=15 pennies

-------------------------------------------------------------------------------------

30.00+10.00+12.00+4.50+1.50+4.20+0.50+0.15+97.23 =

$106.08 Total Deposit

2x+10(340/139)=-18

Answers

Answer:

To solve the equation 2x + 10(340/139) = -18, we can follow these steps:

1. Distribute the 10 to the terms inside the parentheses:

2x + (10 * 340/139) = -18

2x + 3400/139 = -18

2. Combine like terms:

2x + 3400/139 = -18

3. Move the constant term to the other side of the equation by subtracting 3400/139 from both sides:

2x = -18 - 3400/139

4. Simplify the right side of the equation:

2x = (-18 * 139 - 3400) / 139

5. Calculate the right side of the equation:

2x = (-2502 - 3400) / 139

2x = -5902 / 139

6. Divide both sides by 2 to isolate the variable x:

x = -5902 / (2 * 139)

x = -5902 / 278

x = -21.2115 (rounded to four decimal places)

Therefore, the solution to the equation 2x + 10(340/139) = -18 is x = -21.2115.

You are walking down a road seeking treasure the real branches of into 3 paths a guard stands in each path you only know that only one of the girls is telling the truth and the other two are lying this is what they say guard one the treasure lies down this path guard to no treasure lies down this path seek elsewhere Garth 3 the first guard is lying

Answers

Answer:

Guard Two

Step-by-step explanation:

Guard two has the path to the treasure because he's telling people that there's no treasure. That makes him suspicious because he might want the treasure for himself

Final answer:

This is a logic puzzle wherein the guards' statements are evaluated based on the given criteria: only one guard is truthful. Upon analysis, we find that only the path guarded by Guard 2 aligns with this criteria, indicating that this is the path you should take to find the treasure.

Explanation:

This is a classic logic problem, often called the 'Liar and Truth-Teller' puzzle. Here's how we can tackle it:

Guard 1 says: 'The treasure lies down this path.'

Guard 2 says: 'No treasure lies down this path, seek elsewhere.'

Guard 3 says: 'The first guard is lying.'

Since we know that only one guard is telling the truth, let's consider if Guard 1 tells the truth. If so, Guard 2 and Guard 3 would be lying, which contradicts the statement of Guard 3 (who confirms Guard 1's statement as a lie).

If Guard 2 is telling the truth (which means there's no treasure on his path), then both Guard 1 and Guard 3 would be lying, which fits our criteria.

If Guard 3 told the truth, this would mean that Guard 1 is lying, but then Guard 2 would also be telling the truth--this contradicts our initial information (only one guard is truthful).

So, based on these evaluations, you should take the path guarded by Guard 2 because he's the only one telling the truth according to the given criteria.
