Answer:

left one on 3rd row

Step-by-step explanation:

using the rules of exponents/ radicals

$a^{-m}$ = $\frac{1}{a^{m} }$

$a^{\frac{m}{n} }$ = $\sqrt[n]{a^{m} }$

given

$12^{-\frac{4}{7} }$

= $\frac{1}{12^{\frac{4}{7} } }$

= $\frac{1}{\sqrt[7]{12^{4} } }$

Four batsmen on a cricket team had a mean of 42.5 runs the other 7 batsmen had a mea of 18 what was the mean number of scored by

Ira Lisetskai [31]

Answer:

The mean score of the entire team is 26.909.

Step-by-step explanation:

Given that four batsmen had a mean of 42.5.

Let $\textbf{B}_{\textbf{i}$ , where $i = 1, 2, 3, \hdots, 11$ denote the batsmen.

From the first statement, we have:

$\frac{B_1 + B_2 + B_3 + B_4}{4} = 42.5$

$\implies B_1 + B_2 + B_3 + B_4 = 42.5 \times 4 = \textbf{170}$

Therefore, the sum of the scores of the first four batsmen is 170.

Now, from the second statement we have:

$\frac{B_5 + B_6 + B_7 + B_8 + B_9 + B_{10} + B_{11}}{7} = 18$

$\implies B_5 + B_6 + B_7 + B_8 + B_9 + B_{10} + B_{11} = 18 \times 7 = \textbf{126}$

That is, the sum of the scores of the remaining 7 batsmen is 126.

Now, to calculate the average(mean) of the entire team, we add the individual scores and divide it by 11.

$\implies \frac{B_1 + B_2 + B_3 + B_4 + B_5 + B_6 + B_7 + B_8 + B_9 + B_{10} + B_{11}}{11} = \frac{170 + 126}{11}$

$= \frac{296}{11}$

$= \textbf{26.90}$ which is the required answer.

The equation y= -5.131x^2 + 31.821x - 3.333 approximates the number of people standing in line to catch a commuter train x hours

GREYUIT [131]

The answer should be D since after 5 am to 7 am only two hours have passed so x=2, and then you plug in the x as 2 and solve it. You might get not around answer like 39.785 but when you round it, it would be 40.

10) The line FG is a diameter of the circle with centre C (6, 1). Given F is (2.-3), find the coordinates of G.

Maurinko [17]

Answer:

Coordinates of the endpoint g is (10,5)

Step-by-step explanation:

The coordinates of a midpoint can be found using the formula;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

In this case, we have the mid point but we want to get the end point

Thus;

(6,1) = (x1 + 2)/2 , (y1-3)/2

x1 + 2 = 2(6)

x1 + 2 = 12

x1 = 12-2

x1 = 10

y1 - 3 = 2(1)

y1 -3 = 2

y1 = 2 + 3

y1 = 5

The coordinates of G are (10,5)
