Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.
Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8
4 is on the y-intercept. the y axis is vertical and the x axis is horizontal.
X² - 5x - 14 = (x - 7)(x + 2)
ANSWER:
Distance between two points W and E = 146 miles and B is the position of B (balloon)
Angle BWE =55 degrees and angle BEW =67 degrees therefore angle WBE = 180-55-67 =58 degrees
Using sine formula
w/sin (55)= b/sin(58)
w= 146{sin 55/ sin 58) =141 miles Step-by-step explanation:
Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Given 2 secants from an external point to the circle.
The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is
9 + 3y = 22 ( subtract 9 from both parts )
3y = 13 ( divide both sides by 3 )
y ≈ 4. 3 cm ( to the nearest tenth )
