Answer:

B. $\frac{4}{5}\cdot\frac{4}{5} \cdot\frac{4}{5}=\frac{64}{125}$

Step-by-step explanation:

(4/5) is raised to a numerical power of 3.

This is NOT $\frac{4}{5}(3)$ and NOT $\frac{4}{5}+\frac{4}{5}+\frac{4}{5}$ .

Instead, (4/5) is being multiplied by itself 3 times.

This is correctly shown by: $\frac{4}{5}\cdot\frac{4}{5} \cdot\frac{4}{5}$

This can be solved by multiplying the numerators and denominators, which also looks like this: $4^3=64$ and $5^3=125$ .

The exact form is: $\frac{64}{125}$ .

The complete expansion is written as: $\frac{4}{5}\cdot\frac{4}{5} \cdot\frac{4}{5}=\frac{64}{125}$

You have the correct option selected.

Answer:

The answer is " $0.99999340657 \sim 1$ ".

Step-by-step explanation:

$Sucess \ probability \ (p) = 94\% \ or\ 0.94\\\\Sample\ numbers\ n = 14\\$

Using formula:

$P(X=r)= ^n C_r \times p^r \times (1-p)^{n-r}$

Let

$\to r=8,9,10,11,12,13 \ or\ 14\\\\$

Substituting the value for all r:

$P(X=8)= 0.00008540547\\\\P(X=9)= 0.00089201264\\\\P(X=10)= 0.00698743233\\\\P(X=11)= 0.03980719025\\\\P(X=12)= 0.15591149513\\\\P(X=13)= 0.37578668058\\\\P(X=14)= 0.42052319017\\$

Therefore,

$P(X>7)= P(X=8)+P(X=9)+....P(X=14)\\\\= 0.99999340657 \sim 1.$

-22 = 6x + 4 Hehehhe I need help agaaaaiiin

UkoKoshka [18]

Hey there!

$Answer:\boxed{x=\frac{-13}{3}}$

$Explanation:$

$-22=6x+4$

Let's start off with flipping the equation.

$6x+4=-22$

Now we need to subtract 4 from both sides of the equation.

$6x+4-4=-22-4\\6x=-26$

Now in our third/last step, we will divide both sides by 6.

$\frac{6x}{6}=\frac{-26}{6}$

$x=\frac{-13}{3}$

$\boxed{x=\frac{-13}{3}}\text{ is the answer.}$

Hope this helps!

Someone please tell formula

ivolga24 [154]

Answer:

(i) Total cost of the flat is Rs. 540000.

(ii) Expenditure incurred on labour is Rs. 150000

Step-by-step explanation:

According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.

(i) The total cost of the flat is represented by the total 360° in the pie chart.

∴ Using unitary method

75° represents Rs. 112500

⇒ 360° represents = $\frac{112500}{75}$ × 360

= Rs. 540000

∴ Total cost of flat = Rs. 540000

(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:

75° represents Rs. 112500

⇒ 100° represents = $\frac{112500}{75}$ × 100

= Rs. 150000

∴ Cost of labour = Rs. 150000
