Mathematics
1 answer:
AVprozaik [17]2 years ago
3 0

Answer:

  • 7) 65°
  • 8) 25°

Step-by-step explanation:

<u>Question 7</u>

Angle formed by 2 chords is half of the sum of the intercepted arcs

  • x = 1/2(72° + 58°) = 1/2(130°) = 65°

<u>Question 8</u>

Angle formed by 2 secants is half of the difference of the intercepted arcs

  • x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°

The men s clothing buyer had a group of 50 jackets priced at $250 each that was selling very slowly. To stimulate sales of these
erastovalidia [21]

Answer:

The answer is $3000.

Step-by-step explanation:

The men's clothing buyer had a group of 50 jackets priced at $250 each.

Total price of jackets = 50\times250=12500 dollars

The buyer reduced the price of the jackets in that group to $200 and 40 jackets were sold.

So, the price for selling 40 jackets is = 40\times200=8000 dollars

Remaining jackets =50-40=10

These were sold at $150 each, totaling to = 10\times150=1500 dollars

So, overall money earned by reducing prices both time = 8000+1500=9500 dollars

And the markdown in dollars = (original price before reducing) minus (educed total price)

= 12500-9500=3000 dollars

So, the answer is $3000.

The mean GPA for 127 residents of the local apartment complex is 1.6. What is the best point estimate for the mean GPA for all r
madam [21]

By the Central Limit Theorem, the best point estimate for the mean GPA for all residents of the local apartment complex is 1.7.

The Central Limit Theorem established that, for a normally distributed random variable X, with mean and standard deviation, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean  and standard deviation ;

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

The sample of 112 residents has a mean GPA of 1.7.

By the Central Limit Theorem, the best point estimate for the mean GPA for all residents of the local apartment complex is 1.7.

Twelve and three tenths more than five and thirteen thousandths of a number d is equal to fifteen and three hundred two thousand
Masja [62]
12 and 3/10 more than 5 and 13/1000 of d equals 15 and 302/1000
12 and 3/10+(5 and 13/1000 times d)=15 and 302/1000
convert to improper fractions
12 and 3/10=123/10
5 and 13/1000=5013/1000
15 and 302/1000=15302/1000

123/10+(5013/1000 times d)=15302/1000
subtract 123/10 from both sides
123/10=12300/1000
(15302-123000)/1000=2698/1000
5013/1000 times d=2698/1000
multiply both sides by 1000/5013 to clear fraction
d=2698/5013
