Hey there :)

27x² is what we are trying to factorise

When factorising, we do not add but we multiply

Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²

Yasmin is right

Which factorization is equivalent to this expression?
grigory [225]

Answer:

10(3x+7)

Step-by-step explanation:

we have the expression:

30x + 70

To factor this expression we need to indentify the components that are common in both terms.

At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:

10*3=30\\10*7=70

so we can substitute this into the expression:

10*3x+10*7

and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:

10(3x+7)

Computers from a particular company are found to last on average for 24 months without any hardware malfunction with a standard
vodomira [7]

Answer:

At least 68% of observations lie between 22 and 26 months.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 24

Standard deviation = 2

22 = 24 - 2

22 is one standard deviation below the mean

26 = 24 + 2

26 is one standard deviation above the mean.

So, by the empirical rule, at least 68% of observations lie between 22 and 26 months.

2/3 of the bedspread is covered in race cars , therefore

1/3 of the bedspread is covered in stripes

to find the fraction of the red stripes

2/4 x 1/3 = 2 / 12 = 1/6
