Answer:

1 5/32

Step-by-step explanation:

First, find common denominators. What you do to the denominator, you must do to the numerator.

First, multiply 4 to both the numerator and denominator of the second fraction:

(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32

Next, add across:

9/32 + 28/32 = 37/32

Simplify. Turn the improper fraction into a mixed fraction:

37/32 = (32 + 5)/32 = 1 5/32

1 5/32 is your answer.

Answer:

37 /32

Step-by-step explanation:

Find the least common denominator or LCM of the two denominators:

LCM of 8 and 32 is 32

For the 1st fraction, since 8 × 4 = 32,

7 /8  =  7 × 4

       8 × 4 =  28 /32

Likewise, for the 2nd fraction, since 32 × 1 = 32,

9 /32  =  9 × 1

          32 × 1 =  9 /32

Add the two fractions:

28 /32 +  9/32 =  28 + 9 /32  =  37 /32

So, 7/8 + 9/32 = 37/32

In mixed form: 1 5 /32

We conclude that:

[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]

Step-by-step explanation:

Given the radical expression

[tex]\sqrt{\left(-81\right)x^2}[/tex]

simplifying the expression

[tex]\sqrt{\left(-81\right)x^2}[/tex]

Remove parentheses:  (-a) = -a

[tex]\sqrt{\left(-81\right)x^2}=\sqrt{-81x^2}[/tex]

Apply radical rule:   [tex]\sqrt{-a}=\sqrt{-1}\sqrt{a},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

                 [tex]=\sqrt{-1}\sqrt{81x^2}[/tex]

Apply imaginary number rule:  [tex]\sqrt{-1}=i[/tex]

                 [tex]=i\sqrt{81x^2}[/tex]

Apply radical rule:   [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]

                  [tex]=\sqrt{81}i\sqrt{x^2}[/tex]

                  [tex]=9i\sqrt{x^2}[/tex]

Apply radical rule:  [tex]\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

                  [tex]=9ix[/tex]

Therefore, we conclude that:

[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]

Answer:

0.262

Step-by-step explanation:

Edge 2021

The probability of getting 2 or more "Winner" caps on 4 bottles of water

is 0.2616.

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.

The binomial probability is, [tex]^nC_xP^xq^{n - x}[/tex].

Let, p be the probability of winning,

Given,  1 out of every 4 bottles has the word "Winner".

Therefore, p = 1/4 and we know q = 1 - p = 3/4.

So, The probability of getting 2 or more "Winner" caps on 4 bottles of water

is P(X ≥ 2) which is, P(X = 2) + P(X = 3) + P(X = 4).

P(X ≥ 2) = [tex]^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].

P(X ≥ 2) = 6(1/4)²×(3/4)² + 4(1/4)³×(3/4) + 1(1/4)⁴×1.

P(X ≥ 2) = 0.2109 + 0.0468 + 0.0039.

P(X ≥ 2) = 0.2616 or 26.16%.

The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.

Given that, we are asked to find the expanded form of 8.478,

The expanded form is :-

8 =  1 place = 8×1

0.4 = 1/10 place = 4×1/10

0.07 = 1/100 place = 7×1/100

0.008 = 1/1000 place = 8×1/1000

Therefore,

8.478 = 8×1+4×1/10×7×1/100+8×1/1000

Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

Answer:

30

Step-by-step explanation:

Add all the measures 50+35+85+65+60= 210

subtract 180 from 210 and you get

210-180 = 30

we use 180 because  Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.
