What is the value of angle v?

Mathematics
1 answer:
Flauer [41]3 years ago
7 0

Answer:

x = 5

Step-by-step explanation:

a) The third interior angle of this triangle is 180 - 20 x.  

The three interior angles must sum up to 180 degrees.

Therefore,  60 + 7x + 5 + 180 - 20x = 180, or

                       65  + 180 - 13x = 180, or

                               65 -  13x     = 0

Finally, 13x = 65, and so x = 5

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is
Viktor [21]

Answer:

There are approximately 171 families in the sample.

Step-by-step explanation:

Percentile meaning:

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

Twenty-four of the families in the sample turned on the television for 23 hours or less for the week. The 14th percentile of the data is 23 hours.

This means that 24 is 14% of the total number of families.

Approximately how many families are in the sample?

Using a rule of three.

24 - 0.14

x - 1

0.14x = 24

x = 24/0.14

x = 171.4

Rounding to the nearest integer

There are approximately 171 families in the sample.

gizmo_the_mogwai [7]

Answer: No. The intervals defined by the margin or error overlap

Step-by-step explanation:

If we think about it, with the worst margins, 55% could be 48% and then the 45% would be 52%, showing there is no clear yes or no and it is possible that the intervals could overlap

Evaluate the polynomial when a.x=0 and b.x=-1<br> x2 – 3x - 7
Arlecino [84]

Answer:

a) -7 & b) -6

Step-by-step explanation:

Here,

a) x = 0

Solution ↦

x2 - 3x - 7 \\  =  0 \times 2 - 3 \times 0 - 7 \\  =  - 7

b) x = -1

Solution ↦

x2 - 3x - 7 \\  =  - 1 \times 2 - 3 \times ( - 1) - 7 \\  =  - 2 + 3 - 7 \\  =  - 9 + 3 \\  =  - 6

1. Fiscal differences

Democrats are usually pro-regulation, and Republicans are for a free market. However, both are pro-capitalism. Examples: 15 dollar minimum wage, Green New Deal

2. Social differences

Democrats tend to be more progressive in social view, meanwhile Republicans tend to want to stick to the traditions. This means LGBT, abortion BLM, etc.  

3. Climate change

Most Democrats recognize that climate change is a problem (they wont do anything about it, but at least they recognize it I guess.) Most Republicans think that climate change is normal and there is nothing to do about it.
