Answer:

Step-by-step explanation:

Mean- add all the numbers up and then divide them by how many numbers there are.

Median-The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Mode-The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs.

18. Find the measure of each numbered angle.

DiKsa [7]

Answer:

m∠1 = 50°, m∠2 = 90°, m∠3 = 40°, and m∠4 = 50°

Step-by-step explanation:

Angles on straight line are equal;

$m \angle1 + 130 = 180$

$m \angle1= 180 - 130 \\ m \angle1= 50$

Vertical angles are equal,

$m \angle4= m \angle \: 1= 50 \degree$

Complementary angles add up to 90°.

$m \angle3 + m \angle4 = 90 \degree \\ 40 + m \angle3 = 90 \degree. \\ m \angle3 = 90 \degree - 50 \degree \\ m \angle3 = 40 \degree$

Angles on straight line adds up to 180°

$m \angle1 + m \angle2 + m \angle3 = 180 \degree$

$40 + m \angle2 + 50 = 180 \\ m \angle2 = 180 - 50 - 40 = 90$

Use the digits 1,3,4,and 7 to create two whole numbers whose product is estimated to be about 600

blagie [28]

34 x 17 (round the 2 numbers)
30 x 20
600

Also, 34 x 17 = 578, which rounds to 600

The answer is 34 and 17

Answer:

see explanation

Step-by-step explanation:

Using the ratio equality for circles

$\frac{arc}{C}$ = $\frac{angleatcentre}{360}$

(a)

Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus

$\frac{45}{C}$ = $\frac{270}{360}$ = $\frac{3}{4}$ ( cross- multiply )

3C = 180 ( divide both sides by 3 )

C = 60 mm

(b)

Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus

$\frac{3.3}{C}$ = $\frac{225}{360}$ ( cross- multiply )

225C = 1188 ( divide both sides by 225 )

C = 5.28 cm

Need help with this math problem

-BARSIC- [3]

z = 37°

Step-by-step explanation:

The exterior angle theorem says that the sum of two internal angles is equal to the exterior angle

In this case the sum of z and z+4 will be equal to z+41

Writing mathematically

$z + z+ 4 = z + 41\\2z+4 = z + 41\\2z -z = 41 -4\\z = 37$

Hence

z = 37°
