Answer:

d. false, (3 × 6) + 4 < 8 + 4 + 32

Step-by-step explanation:

We want to determine whether, (3 × 6) + 4 = 8 + 4 + 32 is a true or false statement.

Let us first of all simplify the LHS of given expresion to get:

(3 × 6) + 4 = 18+4=22

The RHS is 8+4+32=12+32=44.

We can see that the LHS is less than RHS.

The correct answer is

d. false, (3 × 6) + 4 < 8 + 4 + 32

Kendra has $6.00 in dimes and quarters. If she has 2 times as many quarters as dimes, how many of each coin does she have?
r-ruslan [8.4K]
Make a system of equations.

\sf0.10d+0.25q=6
\sf~q = 2d

Plug in 2d for 'q' in the first equation:

\sf0.10d+0.25q=6

\sf0.10d+0.25(2d)=6

Multiply:

\sf0.10d+0.50d=6

Combine like terms:

\sf0.60d=6

Divide 0.60 to both sides:

\sf~d=10

Now plug this into any of the two equations to find 'q':

\sf~q = 2d

\sf~q = 2(10)

\sf~q = 20

So she has 10 dimes and 20 quarters.

Find the value of x, y, and z if<br> 5<br> X=<br> y =<br> Z=
BlackZzzverrR [31]

Answer:

x = 12

y = 9

z = 11

Step-by-step explanation:

so, let's just do all the calculations in there :

(3×5)⁴ = 3⁴×5⁴

(2×3)⁵ = 2⁵×3⁵

(2×5)⁷ = 2⁷×5⁷

multiplying all 3 terms is then

3⁴×5⁴×2⁵×3⁵×2⁷×5⁷

more let's "group" and combine these terms based on the bases of the power operations, as we need to get an expression showing 2, 3 and 5 with their powers.

so, for the base of 2 we have

2⁵×2⁷ = 2¹²

for the base of 3 we have

3⁴×3⁵ = 3⁹

fire the base of 5 we have

5⁴×5⁷ = 5¹¹

so we get

2¹² × 3⁹ × 5¹¹

=>

x=12

y=9

z=11

To determine whether or not they have a certain desease, 304 people are to have their blood tested. However, rather than testing
Artyom0805 [142]

Answer:

The expected number of tests necessary for the entire group of 304 people is 180.0325

Step-by-step explanation:

Probability of person being positive = p = 0.04

Probability of person being negative = q = 1-0.04=0.96

Number of people in each group = 19

We will use binomial over here

Probability of no test positive :

P(x=0) = ^{19}C_0 (0.04)^0 (0.96)^{19} =0.460419201958

P( at least one tests positive) = 1-P( no one tests positive)= 1-0.460419201958= 0.539580798042

Expected number of tests for each group = 1(0.460419201958)+20(0.539580798042) = 11.2520351628

Number of groups =\frac{\text{Total population}}{\text{no. of people in each group}}=\frac{304}{19}=16

Expected number of tests necessary for the entire group of 304 people:

=\text{Expected number of tests for each group} \times \text{No. of groups}

=11.2520351628 \times 16

=180.0325

Hence The expected number of tests necessary for the entire group of 304 people is 180.0325
