. On a school field trip, the school requires that there are 6 teachers for every 90 students. If 135 students attend the trip h

mr_godi [17]

Answer:

For 135 students , the number of teacher requires is 9

Step-by-step explanation:

Given as :

The number of teacher = 6

The number of student = 90

∵ For 90 students , the number of teacher requires = 6

So , For 1 student , the number of teacher requires = $\frac{6}{90}$

= $\frac{1}{15}$

∴ For 135 student , the number of teacher requires = $\frac{1}{15}$ ×135

Or, For 135 student , the number of teacher requires = $\frac{135}{15}$

So, For 135 student , the number of teacher requires = 9

Hence For 135 students , the number of teacher requires is 9 Answer

In wxy x=y, wx= 9x-11, xy= 4x-1, and wy= 7x-3, find x and the measure of each side

worty [1.4K]

Answer:

WX = WY

9x - 11 = 7x - 3..........Then subtract 7x to the other side such that

2x - 11 = -3..........Then add 11 to both sides such that

2x = 8...........Then divide 2 such that

x = 4

Now we can find each side such that

WX = 9(4)-11 = 25

WY = 7(4)-3 = 25

XY = 4(4)+1 = 17

I need help with number 4!

lesya692 [45]

Answer:

x = -8, y = 6

Step-by-step explanation:

x + 2y = 4 ------(1)

x + y = - 2

y = - x - 2 ----------(2)

Substitute y in (1)

x + 2(- x - 2) = 4

x - 2x - 4 = 4

- x = 4 + 4

x = -8

Substitute x in (2)

y = - (- 8) - 2 = 8 - 2 = 6

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 445445 gram setting. Is

marusya05 [52]

Answer:

Yes there is sufficient evidence.

Null hypothesis; H_o ; μ = 445

Alternative hypothesis; H_o ; μ ≠ 445

Step-by-step explanation:

The null hypothesis states that there is no difference in the test which is denoted by H_o. However, the sign of null hypothesis is denoted by the signs of = or ≥ or ≤.

Meanwhile, the alternative hypothesis is one that defers from the null hypothesis. This therefore implies a significant difference in the test. Thus, the signs of alternative hypothesis is denoted by; < or > or ≠.

Now, the question we have is a two tailed test. Thus;

The null hypothesis is;

bag filling machine works correctly at the 445 gram setting which is;

H_o ; μ = 445

The alternative hypothesis is;

bag filling machine works incorrectly at the 445 gram setting which is;

H_o ; μ ≠ 445
