Answer:
He can choose between 2 for the first, 2 for the second and 2 for the third. Every choice does not influence anything.
Step-by-step explanation:
Answer:
He can make <u>128</u> one third pound of hamburgers using all the ground beef.
Step-by-step explanation:
Given:
Jon is making hamburgers for a church lunch. He has 42 and two thirds lbs of ground beef.
Now, to find the number of one third pound hamburgers can he make using all the ground beef.
Pound of ground beef he has =
Pound of hamburgers he can make = .
Now, to get the number of hamburgers he can make by using all the ground beef we divide the quantity of ground beef by :
<em>As, the division changes into multiplication one of the fraction get reciprocals.</em>
<em><u>Thus, 128 hamburgers he can make.</u></em>
Therefore, he can make 128 one third pound of hamburgers using all the ground beef.
Answer:
C. Approximately normal
Step-by-step explanation:
We know that when we have, np≥10, and n(1−p)≥10, and both of these are true, where n is the sample size, and p is the sample of proportions, the sampling proportions of sample distributions, will be normal in shape.
Expected successes : np=125(0.88)=110≥10
Expected failures : n(1−p)=125(1−0.88)=15≥10
Answer:
83 m (nearest metre)
Step-by-step explanation:
This can be modeled as a <u>right triangle</u>, where the base is 60 m and the height is the height of the building.
<u>Alternate Interior Angles Theorem (Z-angles)</u>
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
Using the Alternate Interior Angles theorem, the angle between the ground and the dashed line (angle of elevation) is 54°.
<u>Tan trigonometric ratio</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = 54°
- O = height of building (h)
- A = 60
Substituting the given values into the formula and solving for h:
