Stove area = 12 square feet
Refrigerator area = 20 square feet
Entire kitchen floor = 270 square feet
12 + 20 = 32 square feet
270 square feet - 32 square feet = 238 square feet
238 square feet will be needed
Answer: a) 1.07, b) 0.1423
Step-by-step explanation:
Since we have given that
n = 1400
Number of voters vote for Republican candidates = 720
So,
And hypothesis are :
(a) What is the z -statistic for this test?
(b) What is the P-value of the test?
p-value = P(Z>Z(statistics))
Hence, a) 1.07, b) 0.1423
Answer:
second option : the side length was multiplied by 5.
Step-by-step explanation:
a = side length of the original square
A² = a×a
(a+5)×(a+5) = a² + 10a + 25
and that should be equal to a²×25
a² + 10a + 25 = 25a² ?
10a + 25 = 24a²
no, that is not true for all a
a×5 × a×5 = a²×25 = 25A²
this is the correct solution, as it is true for all a.
Answer:
Step-by-step explanation:
A+B+C=180
2x+x+90=180 ( the 90 comes from the right angle in the given triangle)
3x=90
x=30°
:) these are all kinda the same strategy.. notice?
