I NEED to know the answer and steps to figure out, Mark wants to paint a mural. He has 1 1/3 gallons of yellow paint, 1 1/4 gall
emmasim [6.3K]
Well, Mark has

1 1/3 of yellow paint

1 1/4 of green paint  and

7/8 of blue paint

now, bear in mind, the yellow is a bucket and 1/3 more, the green one is one bucket and 1/4 more and the blue is 7/8 which is almost 8/8, so is almost a bucketfull.

Then he's going to use 3/4 of each, so, we'd have to subtract 3/4 from each, and there'll be some left still in the paint bucket.

How many will he have left altogether?  well, we simply add the leftovers.

\bf 1\frac{1}{3}\implies \cfrac{1\cdot 3+1}{3}\implies \cfrac{4}{3}
\\\\\\
\cfrac{4}{3}-\stackrel{\downarrow }{\cfrac{3}{4}}\implies \cfrac{16-9}{12}\implies \boxed{\cfrac{7}{12}}\\\\
-------------------------------\\\\
1\frac{1}{4}\implies \cfrac{1\cdot 4+1}{4}\implies \cfrac{5}{4}
\\\\\\
\cfrac{5}{4}-\stackrel{\downarrow }{\cfrac{3}{4}}\implies \cfrac{5-3}{4}\implies \cfrac{2}{4}\implies \boxed{\cfrac{1}{2}}\\\\
-------------------------------\\\\

\bf \cfrac{7}{8}-\stackrel{\downarrow }{\cfrac{3}{4}}\implies \cfrac{7-6
}{8}\implies \boxed{\cfrac{1}{8}}\\\\
-------------------------------\\\\
\textit{so the leftovers are }\cfrac{7}{12}+\cfrac{1}{2}+\cfrac{1}{8}\implies \cfrac{14+12+3}{24}\implies \cfrac{29}{24}\implies 1\frac{5}{24}

Absorption rates into the body are important considerations when manufacturing a generic version of a brand-name drug. A pharmac
Darya [45]

Answer:

Correct option: (D).

Step-by-step explanation:

A null hypothesis is a hypothesis of no difference. It is symbolized by <em>H₀</em>.

A Type I error is the probability of rejection of the null hypothesis of a test when indeed the the null hypothesis is true.

The type I error is also known as the significance level of the test.

It is symbolized by P (type I error) = <em>α</em>.

In this case the researcher wants to determine whether the absorption rate into the body of a new generic drug (G) is the same as its brand-name counterpart (B) or not.

The hypothesis for this test can be defined as:

<em>H₀</em>: The absorption rate into the body of a new generic drug and its brand-name counterpart is same.

<em>Hₐ</em>: The absorption rate into the body of a new generic drug and its brand-name counterpart is not same.

The type I error will be committed when the null hypothesis is rejected when in fact it is true.

That is, a type I error will be made when the the results conclude that the absorption rate into the body for both the drugs is not same, when in fact the absorption rate is same for both.

Thus, the correct option is (<em>D</em>).

Help me iv been trying from this morning
GalinKa [24]

Answer:

i did the first

Step-by-step explanation:

1st way

Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5

y = -2/3*X^2-16/3*X-17/3

X = -4 ±√( 15/2) = -6.7386, or -1.2614

Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)

two real roots: X=-1.2613872124776866 and -6.738612787477313
