maksim [4K]

Answer:

$200L+$100B ≥$5000

Step-by-step explanation:

Given :

Hyun Yong wants to donate more than $5000 in laptops and bicycles.

Each laptop that he donates is worth $200, and each bicycle that he donates is worth $100.

To Find : An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.

Solution :

L denotes the number of laptops.

Since cost of each laptop is $200

Thus cost of L laptops = $200L

B denotes the number of bicycles.

Since cost of each bicycle is $100.

Thus cost of B bicycles = $100B

Now, he wants to donate more than $5000 in laptops and bicycles

So, inequality will be : $200L+$100B ≥$5000

Hence, An inequality that represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal:

$200L+$100B ≥$5000

Given that a professor teaches a certain section of material using a lot of examples with sports and cars to illustrate. He is concerned that this may have biased his instruction to favor male students

Since simple variances are unequal, we can do t test for comparison of two means with unequal variances

$H_0 : \bar x =\bar y\\H_a : \bar x \neq \bar y$

Group Group One Group Two

Mean 84.00 78.00

SD 4.00 8.00

SEM 1.26 2.53

N 10 10

The mean of Group One minus Group Two equals 6.00

95% confidence interval of this difference: From 0.06 to 11.94

t = 2.1213

df = 18

standard error of difference = 2.828

The two-tailed P value equals 0.0480

Since p <0.05 we reject null hypothesis

There is difference in the scores of males and females

In this figure, AB¯¯¯¯¯∥CD¯¯¯¯¯ and m∠6=75°.

Anastaziya [24]

Answer is 105 degrees.

Explanation:

Given two parallel lines AB and CD and a transversal cutting the two lines.

We know that when a transversal cuts two parallel line,

i) corresponding angles would be equal

ii) Interior angles total to 180

iii) alternate angles are equal.

In the picture given we have corresponding angles as

(2,6) . Hence angle 2 = angle 6.

Angle 6 = 75 (given)

Hence angle 2 =75.

Angles 1 and 2 are supplementary because they form a linear pair.

Hence angle 1 = 180-75

Angle 1 =105
