Answer:
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication! Dilation with scale factor 2, multiply by 2.
Answer: Decimal: 0.875 Percent: 87.5%
Step-by-step explanation:
<span>This is a tricky question that Reina and Sam are multiplying (84)5 (73)9
and their work are
</span><span>(84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's
(84)5 (73)9 = 84⋅573⋅9 = 820727 Sam's
Actually they are doing or multiplying using exponents.
</span>
Reina’s work
(8⁴)₅(7³)⁹=8⁴⁺⁵+ 7³⁺⁹= 8⁹ 7¹²<span>
This is incorrect because she added exponents
instead of multiplying exponents
Sams work (8</span>⁴<span>)</span>⁵<span> (7</span>³<span>)</span>⁹<span>=8</span>⁴ˣ⁵<span> 7</span>³ˣ⁹<span>= 8</span>²⁰<span> 7</span>²⁷<span>
<span>This is correct because Sam multiplied exponents correctly</span></span>
<span><span>Exponents are multiplied not added.</span></span>
"The quotient of" tells you to use division. The order tells you which is the numerator and which is the denominator respectively.
n/6 is your answer. Or 
Answer:
A. P=0.4013
B. P=0.9884
C. P=0.3222
Step-by-step explanation:
We can model this with a binomial random variable.
The sample size is n=10.
The probability is p=0.05 for scrap and p=0.05+0.15=0.20 for degraded or scrap.
The probability of having k scrap gears in the sample is:
The probability that one or more is scrap can be calculated as 100% less the probability that no one is scrap:
The probability that 8 or more are not scrap is equal to the probability of having 2 or less that are scrap:
The probability that more than two are degraded or scrap (p=0.2) is calculated as:
