Answer:
<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit = 1.7 cm</em>
Step-by-step explanation:
<u><em>Explanation:</em></u>-
<em><u>step(i):</u></em>-
Given mean of population = 50 cm
<em>standard deviation of Population = 5 cm</em>
<em>Given Margin of error = 10 cm</em>
<em>The Margin of error is determined by </em>
<em></em>
<em></em>
<u><em>Step(ii)</em></u><em>:-</em>
<em>Given level of significance ∝ = 99 % or 1 %</em>
Z₀.₀₁ = 2.576
√n = 1.3
squaring on both sides , we get
<em>n = 1.69≅ 1.7 cm</em>
<u><em> Final answer:</em></u>-
<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit = 1.7 cm</em>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question
y = 7/5x - 3
Comparing with the above formula
<h3>Slope / m = 7/5</h3><h3>c/ y intercept = - 3</h3>
Hope this helps you
Answer:
x is less than -3
Step-by-step explanation:
3x^2+9x<0
x^2+3x<0
x(x+3)<0
x+3<0
x<-3
If you make a proportion,
12 18
--- = ---
10 x
when you cross multiply
12x=180
x=15
EF= 15
Answer:uidelines called the order of operations, which outlines the order in which parts of an expression must be simplified.
ORDER OF OPERATIONS
When simplifying mathematical expressions perform the operations in the following order:
1. Parentheses and other Grouping Symbols
Simplify all expressions inside the parentheses or other grouping symbols, working on the innermost parentheses first.
2. Exponents
Simplify all expressions with exponents.
3. Multiplication and Division
Perform all multiplication and division in order from left to right. These operations have equal priority.
4. Addition and Subtraction
Perform all addition and subtraction in order from left to right. These operations have equal priority
