The x intercepts of the graph of f(x)= x(x+1)(x-5)(x-7) are {0 or 1}, {-1 or 1}, {5 or -5} & {7 or -7}?

1 answer:

7 0

X-intercepts if f(x) = 0
f(x) = x(x + 1)(x - 5)(x - 7)
f(x) = 0 if x = 0 or x +1 = 0 or x - 5 = 0 or x - 7 =0
Answer: {-1 or 0 or 5 or 7}

Let $X$ be the random variable denoting the number of girls that are born. Then $X$ has a binomial distribution on $n=125$ babies and probability of getting a girl $p=0.5$ . The probability we want is

$\mathbb P(X\ge60)=\displaystyle\sum_{x=60}^{125}\binom{125}x0.5^{125-x}0.5^x\approx0.704=70.4\%$

The scale factor from Figure A to Figure B is 4

<h3>How to determine the scale factor from Figure A to Figure B?</h3>

From the question, we have the following statement:

Figure B is a scaled copy of Figure A.

The corresponding side lengths of figure A and figure B are:

Figure A = 10

Figure B = 40

The scale factor from Figure A to Figure B is then calculated as:

Scale factor = Figure B/Figure A

Substitute the known values in the above equation

Scale factor = 40/10

Evaluate the quotient

Scale factor = 4

Hence, the scale factor from Figure A to Figure B is 4

There are 45 vehicles in a parking lot. Three fifths of the vehicles are minivans. How many of the vehicles in the parking lot a

suter [353]

Answer: There are 27 minivans out of the vehicles in the parking lot.

Step-by-step explanation:

Since we have given that

Number of vehicles in a parking lot = 45

Part of the vehicles are minivans is given by

$\frac{3}{5}$

Number of vehicles in the parking lot are minivans is given by

$\frac{3}{5}\times 45\\\\=3\times 9\\\\=27$

Hence, there are 27 minivans out of the vehicles in the parking lot.

Ghella [55]

(a,7) lies on the equation of 5x-y=8, that means we solve for x when y=7.

5x-(7)=8
5x=8+7=15
x=3
=>
a=3
