1 meter of ribbon costs $3 how much do you pay for 2 3/4 If correct I will brainest u

defon

Answer:

You pay $8 $\frac{1}{4}$ for 2 $\frac{3}{4}$ meters of ribbon

Step-by-step explanation:

Let us solve the question

∵ 1 meter of ribbon costs $3

∵ We need to find the cost of 2 $\frac{3}{4}$ meters

→ Separate the length of the ribbon to a whole number and a fraction

∵ The length of the ribbon = 2 m + $\frac{3}{4}$ m

→ Multiply each part by the cost of 1 meter

∵ The cost of 1 meter = 3 dollars

∴ The cost of the ribbon = 3 × 2 + 3 × $\frac{3}{4}$

∴ The cost of the ribbon = 6 + $\frac{9}{4}$ dollars

→ Change the improper fraction $\frac{9}{4}$ to a mixed number

∵ 9 ÷ 4 = 2 $\frac{1}{4}$

∴ The cost of the ribbon = 6 + 2 + $\frac{1}{4}$

∴ The cost of the ribbon = 8 + $\frac{1}{4}$

∴ The cost of the ribbon = 8 $\frac{1}{4}$ dollars

∴ You pay $8 $\frac{1}{4}$ for 2 $\frac{3}{4}$ meters of ribbon

Parking at a large university can be extremely difficult at times. One particular university is trying to determine the location

Anna007 [38]

Answer:

The phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

From the provided data the 95% confidence interval for the population mean parking time of students from within the various college on campus is:

CI = (9.1944, 11.738)

This 95% confidence interval implies that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738) with a specific probability or confidence of 95%.

Thus, the phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
