<h2>Irregular Figure</h2>

\normalsize\blue{\overline{\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad \ \ \ }}

Answer:

<h2>Figure Number 1.</h2><h2 />

Area of smaller square = \tt\underline{5cm}\tt{\times 5cm = }\tt\underline\green{25} \tt{sq.cm}

Area of bigger square = \tt{15cm \times}\tt\underline{ 15cm }\tt{=} \tt\underline\green{225} \tt{sq.cm}

Total Area = \tt\underline\green{25sq.cm} \tt{+} \tt\underline\green{225sq.cm} \tt{=} \normalsize \underline{\boxed{\tt \red{250}}} \tt\underline{sq.cm}

\\

<h2>Figure Number 2.</h2>

Area of square A = \tt\underline{7m}\tt{\times}\tt\underline{7m}\tt{=}\tt\green{49} \tt{sq.m}

Area of square B = \tt{7m}\tt{\times}\tt{7m}\tt{=}\tt\underline\green{49} \tt{sq.m}

Area of square B = \tt{14m}\tt{\times}\tt\underline{14m}\tt{=}\tt\green{196} \tt{sq.m}

Total Area = \tt\underline\green{49m} \tt{+} \tt\underline\green{49m} \tt{+} \tt\underline\green{196} \tt{=}\normalsize \underline{\boxed{\tt \red{294}}}\tt{sq.m}

====================================

To find the area of square use this formula \large\tt{A = s \times s}. Means side of the square multiply to the same side of the square

The proportion of brown M&amp;M's in a milk chocolate packet is approximately 14%. Suppose a package of M&amp;M's typically cont
marshall27 [118]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the scenario above :

A) State the random variable.

The random variable is the p opoertion of brown M&M's in a milk chocolate packet.

B.) Argue that this is a binomial experiment.

Each trial is independent for a total number of 52 trials with a set probability of success at 0.14

C) probability that 6 M&M's are brown:.

P(x) = nCx * p^x * (1-p)^(n-x)

p = 0.14 ; (1 - p) = 0.86 ; n = 52 ; x = 6

P(x = 6) = 52C6 × 0.14^6 × 0.86^46

= 20358520 × 0.00000752954 × 0.00097035078

= 0.1487

D) P(x =25)

P(x = 25) = 52C25 × 0.14^25 × 0.86^27

= 477551179875952 × 449.987958058*10^(-24) × 0.01703955245

= 0.00000000366

E) P(x = 52)

P(x = 52) = 52C52 × 0.14^52 × 0.86^0

= 1 × 3968.78758299*10^(-48) × 1

= 3968.78758299*10^(-48)

F) yes it would be unusual, because such probability is extremely low. However, if a huge or substantial number of trials such may occur

SELECT ALL THAT APPLY. In a population of 250 students, 60% are Whites, 20% are Latinos, 15% are Blacks, and 5% others. In a pro
Sophie [7]

In a proportionate stratified sample of 120, there are 72 Whites, 24 Latinos, 18 Blacks and 6  others.

Proportionate Stratified Sample

A proportionate stratified sample is one in which the size of the strata in the sample is proportional to the size of the strata in the population; in other words, the chance of selecting a unit from a stratum depends on the relative size of that stratum in the population.

Calculating the Proportionate Stratified Sample

The given percentage of -

Whites = 60%

Latinos = 20%

Blacks = 5%

Strength of the sample = 120

⇒ Number of Whites = 60% of 120

= 0.6 × 120

=72

Number of Latinos = 20% of 120

= 0.2 × 120

=24

Proportionate Stratified Sample of Blacks and Others

Count of Blacks = 15 % of 120

= 0.15 × 120

= 18

Count of others = 5% of 120

= 0.05 × 120

6

Thus, in a Proportionate Stratified Sample of 120, 72 are Whites, 24 are Latinos, 18 are Blacks, and 6 are others.
