Answer:

Angles: 42°, 114°, 24°, 30°, 150°.

Step-by-step explanation:

Pie Charts

They represent the comparative values of a given variable subject to study. The whole pie is cut in angular sections where all the angles must sum 360°. If the sum of all the values is S and one particular value is x, then the angle of its circular section is given by

[tex]\displaystyle angle=\frac{x}{S}\ 360^o[/tex]

We have the staff of an office is S=60. When asked about their favorite type of takeaway we get:

Pizza: 7. Its corresponding angle is

[tex]\displaystyle angle=\frac{7}{60}\ 360^o=42^o[/tex]

Curry 19.

[tex]\displaystyle angle=\frac{19}{60}\ 360^o=114^o[/tex]

Fish & chips 4

[tex]\displaystyle angle=\frac{4}{60}\ 360^o=24^o[/tex]

Kebab 5

[tex]\displaystyle angle=\frac{5}{60}\ 360^o=30^o[/tex]

Other 25

[tex]\displaystyle angle=\frac{25}{60}\ 360^o=150^o[/tex]

We can see the sum of all angles is 360°

Answer:

none of the males or females could be colorblind, assuming that this question is referring to x-linked recessive inheritance patterns.

Explanation:

if it is an x linked recessive trait, then the male's genotype is , with (b) representing colorblindness and (B) representing normal vision. the female, who is h o m o z y g ou s for normal vision, would have the genotype .

It would be impossible for the dad to pass on his colorblind gene to a son, because he can only pass a Y chromosome to the son. and a daughter would get the colorblind gene, but the normal gene donated by the mom would dominate it so the daughter could not actually be colorblind
