What is simple interest?

The principal of a loan or the first deposit into a savings account serves as the basis for simple interest. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

P=$26,000  r=2.6%=0.026

A=2P=2(26,000)=$52,000

A=P+Prt

Substitute the known values

52,000=26,000+(26,000×0.026t)

52,000-26,000=676t

The measure of side AC in the triangle is 2.7 m

From the question, we are to determine the measure of AC

From the given information, we have that ΔADC is similar to ΔCDB

Thus,

We can write that

|DC| / |DB| = |AC| / |CB|

From the diagram,

|DC| = 5.5 m

|DB| = 6.3 m

|AC| = h

|CB| = 3.1 m

Then,

5.5 / 6.3 = h / 3.1

∴ h = (5.5 × 3.1) / 6.3

h = 17.05 / 6.3

h = 2.70635 m

h ≈ 2.7 m

Hence,

The length of AC is 2.7 m

Step-by-step explanation:

"axes" is the plural of axis. The x-axis is the flat line marked with numbers and arrows at the ends. Its labelled x on the right side.

The y-axis is the up-and-down line marked with numbers and arrows at the ends, labelled y at the top.

The origin is where the two axes cross.

Points J, E, X and P are all on the axes. But X and E are 5 units from the origin (where the lines cross) J and P are 9 units from the origin.

2, 6 and 10 were labelled on the axes, but each tick mark is an evenly spaced amount. So the 5 was unlabelled, but it is understood to be 5. See image.

The money spent by Mr. Dunston is $ 35.

Given that:-

Money spent by Mr. Dunston and Mr. Dolland = $ 45

Money spent by Mr. Dunston and Ms. Campbell = $ 65

Let the money spent by Mr. Dunston be $ x,

Let the money spent by Mr. Dolland be $ y and,

Let the money spent by Ms. Campbell be $ 3y

Hence, from the data given in the question, we can write,

Step-by-step explanation:

The value of g after solving the expression, 5/2-2g = 5g/2-3+g, is 1.

According to the question,

We have the following expression:

5/2-2g = 5g/2-3+g

Now, moving the terms with the same variables on one side and the integers on another side.

Note that when we move any number of term from one side to another which is in addition or subtraction will result in change of the sign from minus to plus and plus to minus.

5/2+3 = 2g+5g/2+g

Taking 2 as the least common factor on the left hand side and right hand side:

(5+6)/2 = (4g+2g+5g)/2

11/2 = 11g/2

The measure of the angle 1, angle 2, angle 3 is 68°, 94°, 25° respectively.

What is angle?

An angle is created where two straight lines or rays meet at a single point. The point from where two lines converge is known as an angle's vertex. The name "angle" comes from the Latin word "angulus," which meaning "corner."

Let's firstly find angle 1,

We  know that, the sum of the all three angles of a triangle is 180°.

So,

18° + 94° + angle 1 = 180°

112° + angle 1 = 180°

angle 1 = 180° - 112°

angle 1 = 68°

Now, we know that, opposite angle are always equal

Therefore,

angle 2 = 94°

Now, again applying the property of triangle that sum of all three angles are equal:

Therefore,

angle 3 + angle 2 + 61° = 180°

angle 3 + 94° + 61° = 180°

At the 1% level of significance, the heat shield for the Komodo spacecraft have average temperature of 191.811° C < x-bar < 196.73° C which is less 200◦C

Type I error is explained below

1% level of significance means that the p value or the probability of the temperature of the new heat shield for Komodo spacecraft being less than 200° C is less than 1%

The range of average temperatures of the shield is given by the formula

= x-bar ± t(s/√n)

Definition of variables

mean, x-bar = 194.37° C

standard deviation, s = 4.29° C

sample size, n = 24

significance level = 1%

confidence level = 1 - significance level = 1 -  0.01 = 0.99 = 99%

z score, z

For sample size less than 30, n < 30. t scores are used

degree of freedom, df = n - 1 = 24 - 1 =23

t score for 99% confidence level and df of 23 = 2.808

substituting into the formula

= x-bar ± t(s/√n)

= 194.37 ± 2.808 (4.29/ √24)

= 194.27 ± 2.4589

= 191.811 ° C < x-bar < 196.73° C
