Mathematics

Answer:

10.1

Step-by-step explanation:

weighted mean = sum of the multiplication of frequency and value /sum of frequency

sum of frequency = 5 + 5 + 5 + 21 = 36

sum of the multiplication of frequency and value = (16 x 5) + (20 x 5) + (16 x 5) + ( 5 x 21) = 365

365/36 = 10.1

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answer:

0.19975

Step-by-step explanation:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Given:

n = 11

r = 9

p = 0.7

q = 0.3

Plugging in values:

P = ₁₁C₉ (0.7⁹) (0.3¹¹⁻⁹)

P = 0.19975

Draw a graph of the circle with equation x²+y²=9.What are the solutions to the system of circle and line when the circle is give

aleksandrvk [35]

Answer:

(-2.23606, 2) and (2.23606, 2)

Step-by-step explanation:

$x^2+y^2=9$

$y=2$

The circle has its center situated at the origin and radius of 3 units

Applying the value of y to the first equation

$x^2+2^2=9$

$\Rightarrow x^2=9-4$

$\Rightarrow x^2=5$

$\Rightarrow x=\sqrt{5}$

$\Rightarrow x=\pm 2.23606$

So, the points where the line will intersect the circle is (-2.23606, 2) and (2.23606, 2)

Hi, i am doing a graded practice test for algerbra 2 and I need some help with a few of the questions, thanks so much.

Mashcka [7]

Given the equation:

$\log _2(7x)+\log _22=1$

As we know: log a + log b = log (ab)

So,

$\begin{gathered} \log _2(7x\cdot2)=1 \\ \log _2(14x)=\log _22 \\ \\ 14x=2 \\ x=\frac{2}{14} \\ \\ x=\frac{1}{7} \end{gathered}$

So, the answer will be x = 1/7
