Answer:

$\huge\boxed{\sf The\ co-efficient\ of\ x\ is\ -4.}$

Step-by-step explanation:

Slope = m = -4

Y-intercept = c = -7 ( Because that is the point where x = 0 )

<u>Equation:</u>

$\sf y = mx+c\\\\y = -4 x+(-7)\\\\y = -4x-7$

So, The co-efficient of x is -4.

Pie

Answer:

#2 is the closest to the actual roots.

Step-by-step explanation:

$12x^{3} -65x^{2} +24x+10=0$

$\frac{2}{3}$ is not a root, but 0.68078 is.

The other roots are -0.24572 and 4.9816. The closest option is #2.

for a class of 24,78% of students got a B or better on the tex How many students is this? Round to a wholenumber

natita [175]

Step 1

Use the ratio of the number to the percentage to get the required answer.

$\frac{Total\text{ number of students}}{\text{The required number of students}}=\frac{Total\text{ percentage of the class}}{\text{Given percentage}}$

Where,

$\begin{gathered} \text{The total number of students = 24} \\ \text{The required number }of\text{ students= x} \\ \text{The total percentage of the class = 100} \\ \text{Given percentage = 78} \end{gathered}$

Step 2

Get the required answer

$\begin{gathered} \frac{24}{x}=\frac{100}{78} \\ 100x=24\times78 \\ 100x=1872 \\ \frac{100x}{100}=\frac{1872}{100} \\ x=\text{ 18.72} \\ \text{Hence} \\ x\approx19students\text{ rounded to a whole number } \end{gathered}$

The number of students that got B or a better grade on the test = 19 students rounded to a whole number.

The 2nd, 6th, 8th terms of an A.P. form a G.P. , find the common ratio and the general term of the G.P.

melisa1 [442]

The terms of an arithmetic progression, can form consecutive terms of a geometric progression.

The common ratio is: $\mathbf{r = \frac{a + 5d}{a + d}}$
The general term of the GP is: $\mathbf{a_n = (a + d) \times (\frac{a + 5d}{a + d})^{n-1}}$
