in a group of 35 children, 10 have blonde hair, 14 have brown eyes, and 4 have both blonde hair and brown eyes. if a child is selected at random, find the probability that the child has blonde hair or brown eyes
Answers
[tex] \frac{14}{35} + \frac{10}{35} - \frac{4}{35} = \frac{4}{7} [/tex]
The solution is, 4/7 is the probability that the child has blonde hair or brown eyes.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
in a group of 35 children, 10 have blonde hair, 14 have brown eyes, and 4 have both blonde hair and brown eyes.
let, the event be A,
i.e. A = if a child is selected at random, that child has blonde hair or brown eyes.
now, we have,
total no of sample space = 35
probability of blonde hair = 10/ 35
probability of brown eyes = 14/35
probability of both blonde hair and brown eyes = 4/35
so, we get,
probability of blonde hair or brown eyes = 14/ 35 + 10/ 35 - 4/35
= 20 / 35
= 4/7
Hence, The solution is, 4/7 is the probability that the child has blonde hair or brown eyes.

Answer:
LCM of 64 and 94= 3008
HCF of 64 and 94= 2
Step-by-step explanation:
Do a venn diagram with the prime factors of 64 on the left, and the prime factors of 94 on the right. If they have the same factors put them in the middle of the venn diagram. Then you multiply everything in the diagram and get the LCM. The HCF is found by multiplying the factors in both lists which is only 2.

What is the surface area of the prism?
Answers
Step 1: Find the area of the bases (triangles)
A = 1/2 * base * height
A = 1/2 * 16 * 6
A = 48
48 + 48 = 96
Area of the triangles = 96 cm^2
Step 2: Find the area of the sides (rectangles)
A = base * height
A1 = 16 * 12
A1 = 192
A2 = 10 * 12
A2 = 120
120 + 120 = 240
240 + 192 = 432 cm^2
Step 2: Add the areas together
96 + 432
528 cm^2

Write the equation of the line that passes through
the points (-1,2) and (6, 3) in slope-intercept form
Answers
m = y2 - y1/x2 - x1
x1 = 6
x2 = -1
y1 = 2
y2 = 3
m = 3 - 2/6 +1
m = 1/7
from this point we now have y = 1/7x + b
all we now need is “b” (intercept) and to find that we’ll plug in one of our given points and solve for b.
3 = 1/7(6) + b
b = 2.14
with the slope and the intercept we have our answer :
y = 1/7x + 2.14
