dedylja [7]

Answer:

-8

Step-by-step explanation:

If we let x and y represent the first and second numbers, respectively, we can write the problem statement as the equations ...

4x +5y = -28
9x +2y = 11

We can multiply the first equation by -9 and add 4 times the second equation to get an equation in y alone:

-9(4x +5y) +4(9x +2y) = -9(-28) +4(11)

-37y = 296 . . . . . simplify

296/-37 = y = -8 . . . . . divide by the coefficient of y

The second number is -8.

Without using a calculator convert the decimal into a fraction 0. 75

mojhsa [17]

Step-by-step explanation:

Decimals can always be put over 1, as they're part of a whole number.

$\frac{0.75}{1}$

Multiply both numerator and denominator by 100:

$\frac{0.75 \times 100}{1\times 100} =\frac{75}{100}$

$\frac{0.75}{1} \: and \: \frac{75}{100} \: are \: fractions \: of \: 0.75$

If we buy 20 pickles what is the experimental probability of winning 5 or more tickets

Mrac [35]

Answer:

$Pr = 0.66$

Step-by-step explanation:

Given

See attachment for complete question

Required

$P(x \ge 5)$

From the attachment, we have:

$S = 2 + 8 + 4+20+21+19+17+5+2+2$

$S =100$ ---- the sample size

Next, we list out all outcomes more than or equal to 5.

i.e.

$x \ge 5$

5 is represented with the vertical blue rectangle (with frequency 21).

So, the other elements are to the right of frequency 21.

So, we have:

$x \ge 5 = 21+19+17+5+2+2$

$x \ge 5 = 66$

The probability is then calculated as:

$Pr = \frac{x \ge 5}{S}$

This gives

$Pr = \frac{66}{100}$

$Pr = 0.66$

12 divided by -5/8 please help me:)

devlian [24]

-19.2

12/(-5/8) means 12*(-8/5)

12*8=96
96/5=19.2

don’t forget the negative sign

so

-19.2
