Answer: 3.5 pounds
Step-by-step explanation:
Cost of 1 pound of tomatoes= $0.58
Thus, to find the quantity of tomatoes Percy bought in $2.03, we need to divide $2.03 by $0.58
⇒ The quantity of tomatoes he bought=
⇒The quantity of tomatoes he bought = 3.5 pounds
Therefore, Percy bought 3.5 pounds of tomatoes .
Answer:
(a) The mean score of test A is 1210.
(b) The mean score of test A is 1210.
(c) The standard deviation of test A is 80.
(d) The value of Q₃ for test A is 1170.
(e) The value of median for test A is 1090.
(f) The value of IQR for test A is 290.
Step-by-step explanation:
The relation between two standardized tests <em>A</em> and <em>B</em> is:
The equation above approximates the relationship between scores on the two tests.
The summary statistics for test B are as follows:
Lowest Score = 21
Mean score = 29
Standard deviation = 2
Q₃ = 28
Median = 26
IQR = 6
(a)
Compute the lowest score on test A as follows:
Thus, the lowest score on test A is 890.
(b)
Compute the mean score of test A as follows:
<h2>Thus, the mean score of test A is 1210.
(c)
Compute the mean score standard deviation of test A as follows:
<h2>Thus, the standard deviation of test A is 80.
(d)
Compute the value of Q₃ for test A as follows:
Thus, the value of Q₃ for test A is 1170.
(e)
Compute the value of median for test A as follows:
Thus, the value of median for test A is 1090.
(f)
Compute the value of IQR for test A as follows:
Thus, the value of IQR for test A is 290.

In the figure shown below
Answer:
A horizontal line segment M K intersects with line segment J L at their midpoint N.
∠J N M =(5x+2)°
∠ LN M=3( x+ 14)°
So, ∠J N M + ∠ LN M =180°[ These two angles form linear pair.Angles forming linear pair are supplementary.]
⇒5 x+ 2+ 3 (x+ 14) =180 [ By Substitution]
⇒ 5 x+2 +3 x+42°= 180°
⇒ 8 x=180°-44°
⇒8 x= 136°
⇒x= 136°÷8
⇒x=17°
So, ∠J N M =5×17 +2=87°
∠ LN M= 3×(17 +14)=3×31=93
∠J N M =∠K N L [Vertically opposite angles]
∠K N L=87°
