Heyo!

Given ,

225 bolts in 24 minutes

So in a minute it can produce = 225/24 = 9.3 = 9 bolts

In 40 minutes it can produce = 9 x 40 = 360 bolts

Susan makes 5 fruit cups for the picnic. In each cup, she has 5 strawberries and 3 kiwi. Joanna uses the same number of total fr

vaieri [72.5K]

Answer:

Susan makes 5 fruit cups

each fruit cup has 5 strawberries and 3 kiwis

so the number of strawberries used is - 5 x 5 = 25 strawberries

and the number of kiwis used - 5 x 3 = 15 kiwis

so the total number of fruits - 25 + 15 = 40 fruits

Joanna uses 40 fruits to make 4 fruit cups

each cup she uses 8 strawberries

therefore total number of strawberries she uses - 8x 4 = 32 strawberries

she has 40 fruits in total and 32 of those are strawberries

the rest are kiwis

number of kiwis = 40 -32 = 8

8 kiwis are there and she has to make 4 cups

so for each cup number of kiwis = 8 / 4 = 2

so each cup has 2 kiwis

Point T is at (-3, 8). What are the coordinates of T' after R(y-axis) o R(x-axis)?

Whitepunk [10]

Given:

Point is T(-3,8).

To find:

The coordinates of T' after $R(y-axis)\circ R(x-axis)$ .

Solution:

We know that, $R(y-axis)\circ R(x-axis)$ means the figure reflected across the x-axis then reflected across y-axis.

If a figure reflected across x-axis, then

$(x,y)\to (x,-y)$

$T(-3,8)\to T_1(-3,-8)$

If a figure reflected across y-axis, then

$(x,y)\to (-x,y)$

$T_1(-3,-8)\to T'(-(-3),-8)$

$T_1(-3,-8)\to T'(3,-8)$

Therefore, the required point is T'(3,-8).

In a set of 25 aluminum castings, four castings are defective (D), and the remaining twenty-one are good (G). A quality control

lianna [129]

Answer:

The sample space for selecting the group to test contains 2,300 elementary events.

Step-by-step explanation:

There are a total of N = 25 aluminum castings.

Of these 25 aluminum castings, n₁ = 4 castings are defective (D) and n₂ = 21 are good (G).

It is provided that a quality control inspector randomly selects three of the twenty-five castings without replacement to test.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!(n-k)!}$

Compute the number of samples that are possible as follows:

${25\choose 3}=\frac{25!}{3!\times (25-3)!}$

$=\frac{25\times 24\times 23\times 22!}{3!\times 22!}\\\\=\frac{25\times 24\times 23}{3\times 2\times 1}\\\\=2300$

The sample space for selecting the group to test contains 2,300 elementary events.
