Answer:

78 girls

Step-by-step explanation:

Ratio is 3:4, so that means the total number of 182 can be divided into 7 parts. 182 divided by 7 is 26, so each part is 26. The ratio of girls is 3, so 3 times 26 is 78. You can check this by putting (3*26)/(4*26) simplifies to 78/104 to 3/4 which is the right ratio

Answer:

(a) 0.1414

(b) 0.1010

Step-by-step explanation:

(a)

The density curve is rectangular in shape.

This implies that the distribution of donations is Uniform.

(b)

Compute the probability of donations at least 85 cents as follows:

$P(X\geq 85)=\int\limits^{99}_{85} {\frac{1}{99-0} \, dx$

$=\frac{1}{99}\times [x]^{99}_{85}\\\\=\frac{99-85}{99}\\\\=0.1414\\\\$

Thus, the proportion of donations that are at least 85 cents is 0.1414.

(b)

Compute the probability of donations between 30 and 40 cents as follows:

$P(30\leq X\leq 40)=\int\limits^{40}_{30} {\frac{1}{99-0}} \, dx$

$=\frac{1}{99}\times [x]^{40}_{30}\\\\=\frac{40-30}{99}\\\\=0.1010$

Thus, the probability of donations between 30 and 40 cents is 0.1010.

The answer should be half (Can be written as .5 or 1/2) because there are only two types of twins, fraternal and identical. So therefore the probability is half
