Plug in the domain in the equation:
f(-3)=(-3)^2-3=6
f(0)=-3
f(1) = -2
f(2)=1
Range{6,-3,-3,1}

In a certain country, the mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg. Assuming that the distr

Degger [83]

Answer:

0.066

Step-by-step explanation:

We solve this question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation

For the question

mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg.

x = 2.5

Hence:

z = 2.5 - 3.27/0.51

z = -1.5098

Probability value from Z-Table:

P(x ≤ 2.5) =P(x < 2.5) = P(x = 2.5) =

=0.065547

Therefore, the proportion of baby boys that are born with a low birth weight is 0.066

An obtuse triangle is formed if there is an angle that has a measure of more than 90 degrees. You can determine if an obtuse angle is formed by two sides of a triangle if it meet this condition:

Let a and b be two sides of a triangle and c is the longest side:
$a^{2} + b^{2} \ \textless \ c^{2}$

So taking your given:

$10^{2} + 15 ^{2}$ < $c^{2}$
100 + 225 < $c^{2}$
325 < $c^{2}$

To get the smallest possible number, just get the square root of both sides:

$\sqrt{325}$ < $\sqrt{c^{2} }$
18.03 < c

So your smallest possible whole number is 19

<span>Its : (1, H), (2, H), (3, H), (4, H), (1, T), (2, T), (3, T), (4, T) When you flip a coin, you can result in heads (H) or tails (T) when you spin a spinner with 4 equal sections, you get 1, 2, 3, or 4 (1, 2, 3, 4) Therefore the 8 combinations are above.

Hope this helps :)</span>
