Answer:

x = 3

Step-by-step explanation:

-9 + 3(-5x + 7) = -33

-9 - 15x + 21 = -33

- 15x + 12 = -33

         -12 = -12

-15x = -45

/-15    /-15

x = 3

For a science report, Doug is measuring widths of mushrooms with a ruler that divides inches as shown. To determine each width,
Serga [27]
From the 3 options listed, both 5.25 in and 6.5 in could be measures found using a ruler with eighth inches marked, because those decimals can be written in terms of eighth fractions.

5.25 $in $ \rightarrow (5 + 0.25) $in $ \rightarrow (5 +  \frac{2}{8} ) $in$ \\ 
6.5 $in $ \rightarrow (6 + 0.5) $in $ \rightarrow (5 +  \frac{4}{8} ) $in$

The other option, 7.1 in, is not a possibility because 0.1 cannot be written as a fraction of 8 that is marked on the ruler.

Shandra's parents put $1,500 in her bank account for college tuition. At an interest rate
gavmur [86]

Answer:

$6,427.99

Step-by-step explanation:

-We first find the effective annual interest rate as follows:

i_m=(1+i/m)^m-1\\\\=(1+0.0825/2)^2-1\\\\=0.084202

#We the use this rate to find the compounded amount after 18 years:

A=P(1+i_m)^n\\\\=1500(1.084202)^{18}\\\\=6427.99

Hence, the amount after 18 years is $6,427.99

Use the binomial expression (p+q)n
zvonat [6]

Answer:

{0.16807, 0.36015, 0.3087, 0.1323, 0.02835, 0.00243}

Step-by-step explanation:

The expansion of (p+q)^n for n = 5 is ...

(p+q)^5 = p^5 +5·p^4·q +10·p^3·q^2 +10·p^2·q^3 +5·p·q^4 +q^5

When the probability p=0.3 and q = 1-p = 0.7 the terms of this series correspond to the probabilities of 5, 4, 3, 2, 1, and 0 favorable outcomes out of 5 trials.

For example, p^5 = 0.3^5 = 0.00243 is the probability of 5 favorable outcomes in 5 trials where the probability of each favorable outcome is 0.3.

___

The attachment shows the calculation of these numbers using a graphing calculator. It lists them in reverse order of the expansion of (p+q)^5 shown above, so that they are the probabilities of 0–5 favorable outcomes in the order 0–5.
