Answer:

0.5

Step-by-step explanation:

probability of event = numbers of ways it can be / total numbers of outcome

even number of a 6-sided die: 2, 4, 6

Total outcome pf one roll: 1, 2, 3, 4, 5, 6,

P(a) = 3 / 6 = 1 / 2

Answer:

Volume of triangular prism is given by formula

Volume of triangular prism = (Area of the base) x 12 (height of the prism)

now plug the given values

216= (area of the base) x 12

216/12 = area of the base

18= area of the base

so, the answer is 18 square cm

Change the expression to a single square root, or its opposite:

aleksley [76]

Answer:

a) $2\sqrt{2}=\sqrt{8}$

b) $-7\sqrt{3} =-\sqrt{147}$

c) $\frac{1}{3} \sqrt{18b} =\sqrt{2.b}$

d) $5\sqrt{y} =\sqrt{25y}$

e) $-6\sqrt{2a} =-\sqrt{72a}$

f) $-0.1\sqrt{200c}=- \sqrt{2c$

Step-by-step explanation:

a) $2\sqrt{2}=( \sqrt{2} )^2.\sqrt{2}=(\sqrt{2})^3 = \sqrt{2^3} =\sqrt{8}$

b) $-7\sqrt{3} =-(\sqrt{7} )^2\sqrt{3} =-\sqrt{7^2.3} =-\sqrt{147}$

c) $\frac{1}{3} \sqrt{18b} =\frac{1}{3} \sqrt{9.2.b} =\frac{1}{3} \sqrt{3^2.2.b} =\frac{1}{3} \times 3\sqrt{2.b} =\sqrt{2.b}$

d) $5\sqrt{y} =\sqrt{5^2} \sqrt{y}=\sqrt{25y}$

e) $-6\sqrt{2a} =-\sqrt{6^2}\sqrt{2a} = -\sqrt{36.2a} =-\sqrt{72a}$

f) $-0.1\sqrt{200c}=-\frac{1}{10} \sqrt{10^2.2c} =-\frac{1}{10}\times10 \sqrt{2c}=- \sqrt{2c$

Determine the number of terms n in each geometric series.<br> 13) a1 = 0.75, r = 4, Sn =1023.75

Gnom [1K]

Answer:

Number of terms: n=6

Step-by-step explanation:

We are given:

a₁ = 0.75

r = 4

Sₙ = 1023.75

We need to find number of terms i.e n

The formula used will be: $S_n=\frac{a(r^n-1)}{r-1}$

Putting values and fining n

$S_n=\frac{a(r^n-1)}{r-1}\\1023.75=\frac{0.75(4^n-1)}{4-1}\\ 1023.75=\frac{0.75(4^n-1)}{3}\\3\times 1023.75=0.75(4^n-1)\\3071.25=0.75(4^n-1)\\4^n-1=\frac{3071.25}{0.75}\\4^n-1=4095\\4^n=4095+1\\4^n=4096$

We know that $4^6= 4096$

$4^n=4^6$

Using Exponent rule: $a^n=a^b => n=b$

$n=6$

So, Number of terms: n=6
