Answer:

Solving the expression: 2\frac{3}{5}\div \frac{2}{3} we get \mathbf{3\frac{9}{10}}

Option A is correct.

Step-by-step explanation:

We need to solve the expression: 2\frac{3}{5}\div \frac{2}{3}

We need to divide both the terms.

Solving:

2\frac{3}{5}\div \frac{2}{3}

First we will convert the mixed fraction into improper one

\frac{13}{5}\div \frac{2}{3}

Now, we will convert division sign into multiplication, the term 2/3 is reciprocated

\frac{13}{5}\times \frac{3}{2}

Now, multiply numerator with numerator and denominator with denominator

\frac{39}{10}

Now, we will convert into mixed fraction

3\frac{9}{10}

So, Solving the expression: 2\frac{3}{5}\div \frac{2}{3} we get \mathbf{3\frac{9}{10}}

Option A is correct.

A monk crossbred plants which can have purple or white flowers and obtained 511 plants with white flowers and 337 plants with pu
Zepler [3.9K]

Answer:

For purple;

P(p) = 337/848 = 0.40

For white;

P(w) = 511/848 = 0.60

Step-by-step explanation:

Given;

Number of plants with purple flowers P = 337

Number of plants with white flowers W = 511

Total T = 337 + 511 = 848

For purple;

the empirical Probability that a plant had purple flowers P(p) is

P(p) = Number of plants with purple flowers/total number of plants

P(p) = P/T

Substituting the values, we have;

P(p) = 337/848 = 0.40

For white;

the empirical Probability that a plant had white flowers P(w) is

P(w) = Number of plants with white flowers/total number of plants

P(w) = W/T

Substituting the values, we have;

P(w) = 511/848 = 0.60

A sports marketing company interviewed 250 Supersport United fans and has found that the average fan spends R101 on non-ticket p
antiseptic1488 [7]

The 90% confidence interval is between R96.94 and R105.06

The confidence (C) = 90% = 0.9, Mean (μ) = 101, standard deviation (σ) = 39, sample size (n) = 250

α = 1 - C = 1 - 0.9 = 0.1

α/2 = 0.1 / 2 = 0.05

The z score of α/2 corresponds with the z score of 0.45 (0.5 - 0.05) which is equal to 1.645

The margin of error (E) is given by:

E=Z_\frac{\alpha }{2} *\frac{\sigma}{\sqrt{n} } \\\\E=1.645 *\frac{39}{\sqrt{250} } =4.06

The confidence interval = μ ± E = 101 ± 4.06 = (96.94, 105.06)

Therefore the 90% confidence interval is between R96.94 and R105.06
