The addition of the given fractions are;

1) -3³/₅ + -1¹/₅

= -4⁴/₅

2) (-3.5) + (-4)

= -7.5

3) 4.5 + (-3)

= 1.5

4) -5³/₅ + 3¹/₅

= - 2²/₅

1) We want to add the fractions as follows;

-3³/₅ + -1¹/₅

= -3³/₅ - 1¹/₅

= -18/5 - 6/5

= -24/5

= -4⁴/₅

2) (-3.5) + (-4)

= -3.5 - 4

= -7.5

3) 4.5 + (-3)

= 4.5 - 3

= 1.5

4) -5³/₅ + 3¹/₅

= -28/5 + 16/5

= - 2²/₅

The average speed required to reach the concert in time is 61 miles per hour.

The average speed required to reach school in time is 27.567 miles per hour.

What is the average speed?

The average speed of an object is defined as the total distance travelled by an object in a particular interval of time or average time. Mathematically, average speed = total distance / total time taken. Its SI unit is m/s.

Calculation of the average speed

We are given that a concert starts in 5 hours and is 305 miles away from the house, i.e. time = 5 hours and distance  305 miles

Then the average speed in miles per hour is given by total distance / total time

Average speed = 305 / 5

= 61 miles per hour

Further, the time taken to reach school is 37 minutes which when converted to hours becomes 37 / 60 hour

The distance between school and home is 17 miles

So, the average speed = total distance / total time

= 17 / (37 / 60)

= (17 × 60) / 37

= 27.567 miles per hour

Hence, the average speed required to reach the concert in time is 61 miles per hour.

The average speed required to reach school in time is 27.567 miles per hour.

Based on the congruence statement triangle △SUN ≈ △FOG, the true statement is SU is Congruent to side FO.

Congruence of the triangle:

Two triangles are said to be congruent if one can be placed over the other so that they coincide (fit together). This means that congruent triangles are exact copies of each other and when fitted together the sides and angles which coincide, called corresponding sides and angles, are equal.

For example,

△ABC ≈ △DEF

then,

Side  AB  corresponds to  DE,BC  corresponds to  EF , and  AC  corresponds to  DF .

Using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7. (see proof below).

Given the equation, y + 2/3 = 3, to prove that y = 7, we have to solve the given equation in other to find the value of y which must be equal to 7.

(y + 2)/3 = 3 [given]

3 × (y + 2)/3 = 3 × 3 [multiplication property of equality]

y + 2 = 9

y + 2 - 2 = 9 - 2 [subtraction property of equality]

y = 7

Thus, using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7.

When we compare the p-value and the significance level is given [tex]\alpha=0.01[/tex], we can see that [tex]p_v < \alpha[/tex], so we can conclude that we have enough evidence to reject the null hypothesis, which is less than 5.7 Mpa at 1% significance.

Given:

Identify the null and alternative hypotheses.

We need to test a hypothesis to see if the true mean is less than 5.7 Mpa; the hypothesis system would be:

If the sample size is 30 and we don't know the population deviation, we should use a t-test to compare the actual mean to the reference value, and the statistic is given by:

The t-test: "Is one of the most common tests for determining whether the mean is (higher, lower, or not equal) to a specified value."

Determine the statistic

We can substitute the following information in formula (1):

The complete question is given below:
When bonding teeth, orthodontists must maintain a dry field. A new bonding adhesive (called "Smartbond") has been developed to eliminate the necessity of a dry field. However, there is concern that the new bonding adhesive is not as strong as the current standard, a composite adhesive. ( Trends in Biomaterials & Artificial Organs, Jan. 2003.) Tests on a sample of 10 extracted teeth bonded with the new adhesive resulted in a mean breaking strength (after 24 hours) of x = 5.07 Mpa and a standard deviation of s = 0.46 Mpa, where Mpa = megapascal, a measure of force per unit area. Orthodontists want to know if the true mean breaking strength of the new bonding adhesive is less than 5.70 Mpa, the mean breaking strength of the composite adhesive. Conduct the appropriate analysis for the orthodontists. Use alpha= 0.01. What is the p-value?

The differences between two samples are more likely to be statistically significant if the samples are and the standard deviations of the samples are: large and the standard deviations of the samples are small.

The solutions to the absolute value equation given by the word phrase; Absolute value of the quantity one third times x plus 9 end quantity minus 3 equals 21 are; x = −99 and x = 45.

It follows from the task content that the solutions to the absolute value equations as given by the word phrase are to be determined.

Given;

| (1/3)x + 9 | - 3 = 21

Add 3 to both sides;

| (1/3)x + 9 | = 24

Hence, the result equations are; (1/3)x + 9 = 24 OR (1/3)x + 9 = -24.

Therefore, we have;

(1/3)x + 9 = 24

(1/3)x = 24 - 9

(1/3)x = 15

x = 45.

Also, considering the other equation;

(1/3)x + 9 = -24

Subtract 3 from both sides;

(1/3)x = -33

Multiply both sides by 3;

x = -99.

Ultimately, the solutions of the equation are;

x = −99 and x = 45.

Therefore, the solutions to the absolute value equation given by the word phrase; Absolute value of the quantity one third times x plus 9 end quantity minus 3 equals 21 are; x = −99 and x = 45.
