( 5 - 2i)2 Write answer in standard form a +bi. Remember you can not have i2 in your answer it is a number.

Answer:

6.7 %

which agrees with answer A in your list.

Step-by-step explanation:

If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :

1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:

0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%

Recall as well that percent error is always expressed as a positive number.

Answer:x= 48.126

Step-by-step explanation:

Just add 7 to all x-coordinates and subtract 9 from all y-coordinates.

S' = -3 + 7 = 4 and 6 - 9 = -3 therefore S'(4, -3)

T' = 0 + 7 = 7 and 7 - 9 = -2 therefore T'(7, -2)

U' = 1 + 7 = 8 and 4 - 9 = -5 therefore U'(8, -5)

V' = -5 + 7 = 2 and 2 - 9 = -7 therefore V'(2, -7)

Step-by-step explanation:

7/9-1/3=480

9/9=?

Answer:

1080

Step-by-step explanation:

We take x to be the number of pennies in the bank at first which filled the bank by a ¹/3

¹/3=×

⁷/9=×+480

⅓ multiply by 3 with both the numerator and denominator to get 3/9

7/9-3/9=4/9

4/9=480

If 4/9=480 what of 9/9

9/9×480÷4/9

Reciprocate 4/9

UW=165

Step-by-step explanation:

5x + 8x-17= 11x +11

13x - 17 = 11x + 11

Subtract 11x and add 17 to both sides:

2x= 28

Divide 2 both sides:

x=14

Plug in x to the equation of UW:

Answer:

The answer above me is wrong, it is C, red triangle.

Step-by-step explanation:

Got it right on a school test.

The red triangle represents the reflection ABC across the y-axis. Option C is correct.

It is described as the modification of both the geometric body's coordinates and form. A two-dimensional transformation is another name for it. Geometric transformations allow for the rotation, translation, reflection, and glide translation of the geometry.

We have to find the triangle that represents the reflection ABC across the y-axis.

A flip is a term for a reflection in geometry. The form is mirrored in a reflection. The line of reflection is a line across which an image will reflect. Every point in a figure is said to mirror the other figure if and only if it is equally spaced from every corresponding point in the other figure.

Since the green and blue triangles are equidistant from the y-axis. The red triangle will represent the reflection ABC across the y-axis

Thus, option C is correct.

Answer:

y≈5.56

Step-by-step explanation:

[tex]\angle KLM=136\\\\\angle KLN=47\\\\\angle NLM=16y\\\\\angle KLM=\angle KLN+\angleNLM\\\\136=47+16y\\\\136-47=16y\\\\136-36-11=16y\\\\100-11=16y\\\\89=16y\\\\y=\frac{89}{16}\\\\y=5.5625[/tex]

Answer:

y = 5.56

Step-by-step explanation:

Use the total, measure KLN = 136⁰ and subtract measure KLN = 47 from measure KLM. Then do 89/16 = 5.5625. Then round to the hundredths, 5.56.

[136 - 47 = 89]

[89 / 16 = 5.5625]

[Round to 5.56]

Answer:

(-oo, 1) U (1, 3) U (3, oo)

Step-by-step explanation:

We have a line with two arrowheads. The arrow heads show us that the numbers in the set continue forever in the negative direction past -5 and in the positive direction past 5. In this case, the set consists of all real numbers except 1 and 3 since they have open circles.

That means the set is from negative infinity to 1, from 1 to 3, from 3 to positive infinity, but leaving out 1 and 3.

Remember that a regular parentheses symbols, ( and ), do not include the number near them and are used for open circles.

Square brackets, [ and ], do include the number near them and are used for closed circles.

Also, infinity and negative infinity are not numbers, so we always use regular parentheses when dealing with infinity or negative infinity.

We need the union of three sets:

from negative infinity to 1, from 1 to 3, from 3 to positive infinity

Answer: (-oo, 1) U (1, 3) U (3, oo)

To convert a percent to a decimal, you move the decimal point to the left two times

Answer: 0.065

Step-by-step explanation:

When we divide 50 by 100 we get 0.5 (a decimal number). So, to convert from percent to decimal: divide by 100, and remove the percent symbol. So for 6.5% divided by 100=0.065

Answer:

-4 is lesser than 0

Step-by-step explanation:

Let as consider the complete ques is : Ray QS bisects ∠PQR. Solve for x and find m∠PQR. m∠PQS = 3x ; m∠SQR = 5x-20.

Given:

Ray QS bisects ∠PQR.

m∠PQS = 3x

m∠SQR = 5x-20

To find:

The value of x and m∠PQR

Solution:

Ray QS bisects ∠PQR. So,

[tex]m\angle PQS=m\angle SQR[/tex]

[tex]3x=5x-20[/tex]

[tex]3x-5x=-20[/tex]

[tex]-2x=-20[/tex]

[tex]x=10[/tex]

The value of x is 10.

Now,

[tex]m\angle PQR=m\angle PQS+m\angle SQR[/tex]

[tex]m\angle PQR=3x+5x-20[/tex]

[tex]m\angle PQR=8x-20[/tex]

Put x=10,

[tex]m\angle PQR=8(10)-20[/tex]

[tex]m\angle PQR=80-20[/tex]

[tex]m\angle PQR=60[/tex]

Therefore, the m∠PQR is 60 degrees.

Answer:

(17.75, 110.32)

Step-by-step explanation:

The sample mean is 64.03, and the standard deviation is 15.43.

The population is normally distributed, so 99.5% confidence is ±3 standard deviations.

The confidence interval is therefore:

(64.03 − 3 × 15.43, 64.03 + 3 × 15.43)

(17.75, 110.32)

The 99.5% confidence interval will be equal to  (17.75, 110.32).

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given data provided by the question,

With a standard deviation of 15.43 and a sample mean of 64.03, respectively.

Since the population has normally distributed, 99.5% probability lies within a range of three standard deviations.

Consequently, the confidence interval is:

= (64.03 − 3 × 15.43, 64.03 + 3 × 15.43)

= (17.75, 110.32), this is up to 2 decimal places.
