Answer:
d.every word in the first sentence of the first page of every chapter.
Step-by-step explanation
- the sample space means the set of total possible outcomes or ALL possible outcomes.
- so here, the situation is about the teacher reading a sentence.
- the favorable outcome is the set which has all the words that the students would not know from all the words read by the teacher or simply from the sample space.
- since the teacher reads the first sentence on the first page in every chapter , all the words in that sentence will be sample in this situation.
Answer:
The length of the flagpole be 41.2 ft .
Option (A) is correct .
Step-by-step explanation:
As given
The angle looking up at the sun is 70°.
A flagpole casts a shadow of 15 ft .
Now by using the trignometric identity .
BC = 15 ft
tan 70° = 2.75 (Approx)
AB = 2.75 × 15
= 41.2 ft
Therefore the length of the flagpole be 41.2 ft .
Option (A) is correct .
Answer:
63 feet of ribbon
Step-by-step explanation:
First, you find the unit rate by dividing 36 by 12. That gets you 3 feet of ribbon per package. Since you need to find how many feet of ribbon are in 21 packages, you multiply 21 and 3. 21x3= 63
Answer:
The answer is: 11.2, 13 and 17.4
Step-by-step explanation:
The scale factor of 2 means that we will build a triangle with sides of double lenght than original one.
So sides will be
Answer:
y = 3x + 5
Step-by-step explanation:
First start at your y intercept (5) and use the rise to run ratio (rise 3, run 1) and there is a point on every single one.
1/3 wouldn't work because you rise 1 and go right 3 and that does not match any of the points
Using the two points first gives us a slope of 3
(1, 8) (2, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 8)/(2 - 1)
m = 3/1
m = 3
We also know that 8 cannot be the intercept being as it is the point at x = 1. Therefore, we know that y = 3x + 5 must be the only possible answer.
