Step-by-step explanation:

We need to find an expression that is equivalent to 4×(8+3)

We know that,

4×(8+3) = 4(11) = 44

Option (1).

(4 • 8) + 3 = 32+3 = 35. It is incorrect

Option (2).

(8 + 3) • 4 = (11) 4 = 44. It is correct.

Option (3).

4 • (3 + 8) = 4(11) = 44. It is correct.

Option (4).

4 • 8 + 4 • 3 = 32+12 = 44. It is correct.

Hence, the correct options are (2), (3) and (4).

On a typical day, a jewelry store sells 8 bracelets. The data show the number of bracelets sold on each day for four weeks at a
mote1985 [20]

For which week would the mean of the data be a good estimate of the jewelry store's weekly sales throughout the year?

Answer: Week 4's mean would be a good estimate of the jewelry store's weekly sales throughout the year. Because the average of the Week 4's sales is 8. Also we can see the Week 4's data appears without outliers. So the option Week 4: 9, 7, 8, 8, 11, 6, 7  would be a good estimate of the jewelry store's weekly sales throughout the year.

<u>Explanation:</u>

Week 1's mean is:

\frac{7+8+7+9+1+6+8}{7} =\frac{46}{7} =6.57

Week 2's mean is:

\frac{6+7+8+7+9+8+17}{7} =\frac{62}{7} =8.86

Week 3's mean is:

\frac{3+1+2+3+2+3+2}{7} =\frac{16}{7} =2.29

Week 4's mean is:

 \frac{9+7+8+8+11+6+7}{7} =\frac{56}{7} =8

Since the week 4's mean is 8, which is same as typical day's sale of bracelet's. Therefore, week 4 will be good estimate of the jewelry store's weekly sales throughout the year.

Answer: a = 14.5 mm
Explanation: Perimeter is the measure of the outside, which to get you just add the outside values together. To find a, you take the perimeter that we know is 34.8 mm and subtract the 11.6 mm and 8.7 mm, which leaves us to have 14.5 mm. We can check that this value is approximately right because it is the hypotenuse, which is the longest side. Since the value is the biggest out of the other two, we can assume that we found the right value.
