Answer is C) 51
Angle y is 62 degrees because it forms a straight line with the angles next to it (57 and 61) so angle y must be 62.
There are 180 degrees in a triangle so 180-62-67 = 51
Answer:
D
Step-by-step explanation:
Because the first equation is equivalent to 1, and d is equivalent to 1, the rest are incorrect
Answer:
1,2,3,4,5,6,7,8,9,10
4,5,6,7,8,9,10
Step-by-step explanation:
Let x=the amount of roses that Brad buys. (x+3)=the number of daisies that Brad buys.
x+(x+3)=33
Simplify this problem to find the amount of roses:
2x+3=33
2x=30
x=15
So, Brad buys 15 roses and 18 daisies.
Since roses cost $3, 15*3=45.
The roses cost $45.
Hope this helps! :)
Answer:
Mean of the Population or The claimed population mean 'μ' = 5.5 hrs.
Mean of the sample 'x⁻' = 6.25 hours
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data A recent article in a college newspaper stated that college students get an average of 5.5 hrs. of sleep each night
Discuss about total college students so
<em>Mean of the Population 'μ' = 5.5 hrs.</em>
Given random sample size 'n =25
Given data the sampled students slept 6.25 hours per night
<em>mean of the sample 'x⁻' = 6.25 hours</em>
