Answer: 8.01
Step-by-step explanation:
Speed = distance/time = 280/4.5 = 62.44mph
Time = distance/speed = 500/62.44 = 8.0071 hrs
The area of this figure is 30 square cm.
Explanation
The figure consists of a rectangle and right angled triangle.
length of the rectangle l=6cm
breadth of the rectangle b=4 cm
area of the rectangle=lb=6*4 =
hypotenuse of the right angled triangle=5 cm
height h=4 cm
we have to calculate the base using pythagoras theorem
area of the triangle=
are of the figure=area of the rectangle+area of the triangle=24+6=30 sq cm
Answer:
(a) The correct option is (A).
(b) The correct option is (B).
Step-by-step explanation:
Nam collected the data for the distance traveled by all the cars in his car lot.
(a)
A histogram is a bar graph representing the distribution of a random variable. The height of the bars of the histogram represents the frequency for a specific interval.
If Nam wants to know how many vehicles had driven more than 200,000 km, the histogram would be the best display of this data. This is because the histogram shows the frequency for various interval values.
The correct option is (A).
(b)
A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,
- Minimum (shown at the bottom of the chart)
- First Quartile (shown by the bottom line of the box)
- Median (or the second quartile) (shown as a line in the center of the box)
- Third Quartile (shown by the top line of the box)
- Maximum (shown at the top of the chart).
So, if Nam wants to find whether the median distance was approximately 140,000 km, a box plot would be a better choice. This is because the box plot represents the median of the data by a line within the box.
The correct option is (B).
Answer:
III. 2
Step-by-step explanation:
To solve out the inequality, first you subtract 2 on each side, leaving you with 2 > -4x. Then, you divide each side by -4. When you divide by a negative, the direction of the sign switches. Therefore, you get -2/4 < x which is -1/2 < x in simplified version. This means that x is anything greater than -1/2. The only answer choice that is greater than -1/2 is III.
I cannno t see that picture bud butttt hope this helps it is 643222 + ( . ) = 2
