Answer:

-213

Step-by-step explanation:

If h(r) = 23r − 6, then, if we choose r = 2 as an example (only), then:

If h(2) = 23(2) − 6 = 46 - 6 = 40

Using the same approach, we substitute -9 for r, obtaining:

If h(-9) = 23(-9) − 6 = -207 - 6 = -213

This does not match any of the given possible answers. Please ensure that you have copied down the problem and possible answers accurately.

Answer:

-213

not in d option though check d question

Step-by-step explanation:

h(r) = 23r − 6

h(-9) = 23(-9) - 6

= -207 - 6

= -213

Answer:

960 ft²

Since you are doing volume, your multiplication sentence would look like

Length * Width * Height

Now, if you multiply 10 * 8 * 12, your answer will be 960 ft²

Hello There!

All you really need to do is multiply 160 with 32.

$160$ × $32$ ≈ $5120$

5120 cm

The following are questions from a self-quiz.According to some study, the height for Northern European adult males is normally d

lara [203]

Answer:

a) 0.064

b) 0.109

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 181 centimeter

Standard Deviation, σ = 7.3 centimeter

We are given that the distribution of height for Northern European adult males is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(person is between 160 and 170 centimeters)

$P(160 \leq x \leq 170) = P(\displaystyle\frac{160 - 181}{7.3} \leq z \leq \displaystyle\frac{170-181}{7.3}) = P(-2.8767 \leq z \leq -1.506)\\\\= P(z \leq -1.506) - P(z < -2.8767)\\= 0.066 -0.002 = 0.064 = 6.4\%$

b) P(person is higher than 190 centimeter)

P(x > 190)

$P( x > 190) = P( z > \displaystyle\frac{190 - 181}{7.3}) = P(z > 1.2328)$

$= 1 - P(z \leq 1.2328)$

Calculation the value from standard normal z table, we have,

$P(x > 190) = 1 - 0.891 = 0.109 = 10.9\%$
