A person can order a new car with a choice of 6 possible colors, with or without air conditioning, with or without automatic tra
ASHA 777 [7]

Answer: 48

Step-by-step explanation:

Given : Number of choices for colors = 6

Number of choices for car with AC or without AC= 2

Number of  choices for car with or without automatic transmission=2

Number of  choices for car with or without a CD player=2

By using FUNDAMENTAL COUNTING PRINCIPLE, the number of different ways that a new car can be ordered is given by :-

6\times2\times2\times2=48

Hence, there are 48 different ways that a new car can be ordered.

WILL GIVE BRAINLIEST
serg [7]

Answer:

It is the second graph, the one with two filled in dots, but no line.

Step-by-step explanation:

The reason it is not the first one is because it has not filled in dots, AND no line, so it's basically saying there is no answer, which is not true.

The reason the third one (the one with a line) is wrong is because, for example, x cannot be 1, because 1 ≠ 2, and if there is a line, it should be true.

Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=10
Tanya [424]

Answer:

a) 0.7734

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 101, \sigma = 24

(a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ?

This is 1 subtracted by the pvalue of Z when X = 83. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{83 - 101}{24}

Z = -0.75

Z = -0.75 has a pvalue of 0.2266

1 - 0.2266 = 0.7734

The answer is 0.7734

Smallest Zero of f(x+5)=x^2+3x+30
WARRIOR [948]
Hey there
_________________
The correct answer is:
f(x+5)=(x+5)^2+3(x+5)-10

f(x+5)=x^2+10x+25+3x+15-10

f(x+5)=x^2+13x+30  and f(x+5)=x^2+kx+30 so

k=13

Now factor x^2+13x+30

Find j and k such that jk=ac=30 and j+k+b=13 so j and k are 10 and 3 so

(x+3)(x+10)

So the two zeros occur when x=-3 and -10 the smallest of which is:

x=-10
