In TUV the measure of V=90 TU=88 and UV=43 feet. Find the measure of T to the nearest tenth of a degree

LekaFEV [45]

Answer:

m∠T = 27.9°

Step-by-step explanation:

Use the law of cosines

$UV^{2} = TU^{2} + UV^{2} - 2(TU)(UV)cos T\\43^{2} = 88^{2} + 90^{2} - 2(88)(90) cos T\\1849 = 7744 + 8100 - 15840 cos T\\1849 = 15844 - 15840 cos T\\-13995 = - 15840 cos T\\cos T = \frac{-13995}{-15840} = .883522...\\T = arccos .883522... = 27.9$

Sophia’s school took a field trip. A total of 21 vechicles were needed for the trip. Some students took the bus, and some studen

Ivenika [448]

Let the number of buses be x

and car be y

• Total vehicle gone are 21

x + y = 21 ..... ( i ) × 4

• There are 30 people in buses and 4 on car total people gone are 318

30x + 4y = 318 ..... ( ii )

Sub ( ii ) from ( i ) × 4

4x + 4y - ( 30x + 4y ) = 84 - 318

4x + 4y - 30x - 4y = - 234

- 26y = - 234

y = 9

Putting the value of y in eq i

x + y = 21

x = 21 - 9

x = 12

Total buses are 12

and total car are 9

Hope it helps...

Answer:

Random variable: for this case represent the number of complaints in 2007

Population parameter: represent the real proportion of complaints in 2007 p

Hypothesis to verify

We want to check if the true proportion of complaints in 2007 is equal to 0.23, the system of hypothesis are.:

Null hypothesis: $p=0.23$

Alternative hypothesis: $p \neq 0.23$

Step-by-step explanation:

Information provided

n=1432 represent the random sample taken

X=321 represent the number of complaints

$\hat p=\frac{321}{1432}=0.224$ estimated proportion of complaints in 2007

$p_o=0.23$ is the value to verify

z would represent the statistic

Random variable: for this case represent the number of complaints in 2007
