Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The percentage of parents that have one child under 18 in their homes is k = 15%
The percentage of parents that have two children is T = 65%
The percentage of parents that have three or more children is Y = 20%
Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as
=>
=>
The number of dimes that Gina has is 4.00 - (y)q.
<h3>What are word problems?</h3>
Word problems in mathematics are real-life situations that can be solved with the use of mathematical expressions (such as algebraic expressions) with the use of variables and their arithmetic operations.
Given that:
- Mona: (x)q + (y)d = 4.75 ----- (1)
- Gina: (y)q + (x)d = 4.00 ----- (2)
From equation (2), since the number of coins Mona has did not influence Gina's Coin;
The number of dimes Gina has is:
(x)d = 4.00 - (y)q

If two chords intersect each other inside a circle, the products of their segments are equal.
If M is midpoint of AB, then AM = MB = 24/2 = 12.
<span>Product of the lengths of the segments AM and MB:
</span>AM * MB = 12 * 12 = 144
<span>So, any chord of circle O that intersects AB at its midpoint, M, wll be separated by M into two segments such that the product of the lengths of the segments is 144.

Answer:
x = 74°
Step-by-step explanation:
The angle whose vertex lies on the circle, that is angle x is one- half the measure of it's intercepted arc, that is
x = 0.5 × 148° = 74°
Answer:
point-slope form: y - 1 = -4/5(x - 8)
slope-intercept form: y = -4/5x + 7.4
Step-by-step explanation:
Find slope using the points (8, 1) and (-2, 9):
m = (y₂ - y₁) / (x₂ - x₁)
= (9 - 1) / (-2 - 8)
= 8 / -10
m = -4/5
Find y-intercept using slope m from above and anyone of the given points, let's use (8, 1):
y = mx + b
1 = -4/5(8) + b
1 = -6.4 + b
b = 7.4
Use slope m and y-intercept b above to form equation of line in slope-intercept form:
y = mx + b
y = -4/5x + 7.4
For point slope form use slope m from above and a point, again let's use (8, 1):
y - y₁ = m(x - x₁)
y - 1 = -4/5(x - 8)
