Answer:
50 cents
Step-by-step explanation:
Let's set up a system of equations. Let x be a cookie and y be a brownie then...
x+2y=2x+y
x+y=1
We can solve this using substitution
x=1-y
1-y+2y=2(1-y)+y
1+y=2-2y+y
1+y=2-y
-1=-2y
y=1/2
One brownie costs 50 cents and one cookie costs...
x+1/2=1
x=1/2
One cookie costs 50 cents
Answer:
The true average mileage of the Libra Using Null hypothesis is as ;
H0:μ≤26
(Ha):μ >26
Step-by-step explanation:
Given:
Libra, will average better than 26 miles per gallon in the city
To Find:
Average mileage of the Libra.
Solution:
This problem is related to the null hypothesis and alternate hypothesis.
i.e Null Hypothesis is the statement which is true and statement which contradictory is called alternate hypothesis.
<em>“reject H0” if the sample information favors the alternative hypothesis.
</em>
<em>“do not reject H0” / “decline to reject H0” if the sample information is insufficient to reject the null hypothesis</em>
So given that condition is libra will have average better than 26
So it will include 26 and above values .
i.e. True condition is called as null hypothesis (H0)
so true average will be greater than 26
So H0:μ≤26
And the Alternate hypothesis will be the contradictory to true condition
(Ha):μ >26 .
Answer:
The correct answer is option D. 48
Step-by-step explanation:
From the figure we can see that, some right angled triangles.
<u>To find the measure of LP</u>
Consider the right angled triangle LPT,
LT is the hypotenuse, LP = 50 units (given)
PT = QT = RT = 14 units
From figure we get,
LP² + PT² = LT²²
LP² = LT² - PT²
= 50² - 14²
= 2500 - 196
= 2304
LP =√2304
= 48
The correct answer is option D. 48
+5
1500 * 0.16 = 240
365 - 240 = 125
125 / 20 = 6.25 per hour
